Answer:

Solids keep their shape and cannot be compressed. Let us see if the particle model can help us understand why solids behave in this way.

In a solid, the particles are packed close to each other in fixed positions. They are locked into place, and this explains why solids have a fixed shape. Look at the following images of sodium chloride (table salt). Do you remember the formula for sodium chloride?

Macroscopic view of sodium chloride

Submicroscopic view of sodium chloride

Table salt crystals are hard and have a fixed shape.

Can you see how the chloride atoms (purple) alternate with the sodium atoms (yellow) in a fixed arrangement?

Take a good look at the picture of the particles in a solid (table salt) above. You will see that they are packed in a regular arrangement. There are very small spaces between the particles in a solid.

Particles are held together by forces of attraction. In solids, these forces are strong enough to hold the particles firmly in position.

Does that mean the particles in a solid do not move at all? No. The particles in a solid move a little bit. They vibrate in their fixed positions. The more energy the particles have, the faster and more strongly they vibrate.

Do you see how we have used the particle model of matter to explain the properties of solids that we can observe? For example, the particles in solids are closely packed and have strong forces between them explains why solids have a fixed shape and you cannot compress them.

The liquid state

An important characteristic of liquids is that they flow. They fill containers they are poured into. Liquids are also not very compressible. How can these properties be explained?

Orange juice is a liquid, which can be poured.

In the liquid state, particles do not have fixed positions. They move about freely, but they stay close together because the forces of attraction between them are quite strong, but not as strong as in solids.

Have you noticed how a liquid always takes the shape of the container it is in? Within the liquid, the particles slip and slide past each other. This is why liquid flows. Their particles are free to move around, filling the spaces left by other particles. Look at the image of the juice being poured. Let's zoom in and have a look at what the particles are doing as the juice is poured.

The particles in a liquid have small spaces between them, but not as small as in solids. The particles in a liquid are loosely arranged which means they do not have a fixed shape like solids, but they rather take the shape of the container they are in.

The speed at which the particles move around inside the liquid depends on the energy of the particles. When we heat a liquid, we are giving the particles more energy and speeding them up.

In gases, the particles move at even greater speeds.

The gaseous state

Gases spread out quickly to fill all the space available to them. Think of when you blow up a balloon. The air that you blow into the balloon fills up the whole balloon. A gas will fill the entire space that is available to it. This is because the particles in a gas have no particular arrangement.

Gases do not have a fixed shape. Think about the balloon again: the gas fills the entire space inside the balloon. You can squeeze the balloon, changing the shape.

Gases fill the space available to them.

Gases do not have a fixed shape.

Gas particles move very fast, much faster than in solids and liquids. The particles in a gas possess a lot of energy.

Have you ever tried to compress the gas in a syringe or in a bicycle pump? Why do you think you can compress the gas?

In gases, the forces between particles are very weak. This explains why the particles in gases are not neatly arranged. They are not held together tightly and there are large spaces between them. These spaces are much larger than in the solid and liquid state.

Explanation:

Answer:

The particle model of matter is one of the most useful scientific models because it describes matter in all three states. Understanding how the particles of matter behave is vital if we hope to understand science!

The model also helps us to understand what happens to the particles when matter changes from one state to another.

The following diagram shows different changes of state, as well as which processes are the reverse of each other. Melting and freezing are the reverse processes of each other and so are evaporation (boiling) and condensation.

Answer:

When temperature is held constant, the pressure and volume of a gas are not proportional.

Explanation:

That is Boyle's Law

Boyle’s Law states that, when temperature is held constant, the pressure and volume of a gas are inversely proportional.

Gas laws are defined as the laws that govern the properties of gases by determining the relationships between the pressure, volume and temperature of the gases.

Here,

Boyle's law is the gas law that governs the relationship between the pressure and volume of gases.

Boyle's law states that, for an ideal gas at a unit mass, the pressure of the gas is inversely proportional to the volume of the gas, at constant temperature.

P [tex]\alpha[/tex] 1/V

PV = a constant

When the temperature of the gas is held constant.

Hence,

Boyle’s Law states that, when temperature is held constant, the pressure and volume of a gas are inversely proportional.

The net force which has to be applied on the arrow of 0.07kg to accelerate at the rate of 4000m/s² is 280N. Thus, the correct option is A.

A force is an influence which can be a push or a pull that can change the motion of an object. A force can cause an object with some mass to change the velocity, i.e., results into acceleration. A force is a vector quantity as it has both the magnitude and direction.

Force applied on an object can be calculated by the formula:

f = m × a

where, f = force applied,

m = mass of the object,

a = acceleration of the object

Therefore, the force applied on the arrow is:

f = m × a

m = 0.07kg

a = 4000m/s²

f = 0.07 × 4000

f = 280N

Therefore, the correct option is A.

The cloth dryer appliance works on the energy transformation from electrical energy into mechanical energy and thermal energy. Hence, option B is correct.

According to energy conservation law, energy can neither be created nor be destroyed but it can be transformed from one form to the other. Thus, energy lost by one form can be gained in other form.

In electrical devices, electrical energy is converting to various other forms. For instance, in lamps, electrical energy is converted to the light energy. Similarly in fan electrical energy is converted to the mechanical energy.

In a cloth dryer the electrical energy is converted to the mechanical energy to make it  operate and this further produces the thermal energy sufficient to dry the clothes.

Explanation:

Autumn start in different months of the year in North America and South America due to the tilt in earth's axis creating different distance from the sun for different regions.

A season is a time of year that can be identified by unique climatic features. Spring, summer, fall, and winter all occur in regular succession. Each has distinctive seasonal variations in light, temperature, and weather.

Each seasons starts at different month in two hemispheres of  earth. This s due to the fact that, earth's axis is not perfectly circular and it is slightly tilted towards sun.

When the Northern Hemisphere is tilted toward the sun in June, more of the day is spent being illuminated by the sun's rays than it is in winter. As a result, there are longer daylight hours.

There are fewer daylight hours in December because the Northern Hemisphere is tilted away from the sun. Similarly the autumn season also differ from that of the southern hemisphere.

The relationship between the evolution of marsupials and the movement of earths tectonic plate is that the marsupials migrated to different continents during the drift.

Evolution is defined as the gradual and cumulative processes by which the traits of biological population and the diversities changed over time.

Here,

The movement of tectonic plates of earth resulted in the continents to break apart into various isolated parts. During this movement of the tectonic plates, the group of organisms that were living at some continents got split from the actual habitats and were driven to different isolated community of organisms.

As a result, the marsupials who were inbreeding within their habitats were reproductively isolated to different parts of the earth. Thus they got adapted to the new areas and resulted in the creation of new species which is called the evolution of marsupials.

Hence,

The relationship between the evolution of marsupials and the movement of earths tectonic plate is that the marsupials migrated to different continents during the drift.

Answer:dew is formed on grass

Explanation:Dew forms when the object, such as the glass, cools down to the dew point temperature. Water molecules in the air continually bombard surfaces, like blades of grass. ... If the object gets cold enough, and there is enough moisture in the air, condensation is much greater than evaporation and the film grows into dew drops.

Explanation:

Dew forms when the object, such as the glass, cools down to the dew point temperature. Water molecules in the air continually bombard surfaces, like blades of grass. ... If the object gets cold enough, and the air contains enough moisture, condensation exceeds evaporation, and the film grows into dew drops

As fall begins, we have lots of mornings with dew on the grass. To explain this, we start with the fact that air contains water in the gas phase, called water vapor. Dew is made of liquid water that has condensed from that water vapor.

Dew occurs when objects cool, such as when drops of liquid form on the outside of an ice-cold drink glass. Dew forms when the object, such as the glass, cools down to the dew point temperature.

Water molecules in the air continually bombard surfaces, like blades of grass. Some of the molecules stick, forming a very thin film of water. This film may not last long, as the water is also evaporating. The evaporation rate depends on the water temperature, which equals the temperature on the grass.

So condensation depends on the state of the atmosphere (primarily temperature and moisture), while evaporation depends on the temperature of the object. If the object gets cold enough, and the air contains enough moisture, condensation exceeds evaporation, and the film grows into dew drops.

Each night the weather report includes the temperature and the dew point temperature. If the two temperatures are close, dew is likely during the night. Because wind and cloudy skies keep the ground from cooling, dew also tends to form on calm nights with clear skies.
