Answer:

When boiling a substance, the particles obtain more kinetic and potential energy from the heat being delivered. The kinetic energy means that the particles starts moving more intensely, and the potential energy means that the particles start to move away further from each other, which means the substance expands in volume.

Explanation:

When a liquid is heated, the particles gain energy and begin to move faster and faster, expanding the liquid. As the liquid warms, the most energetic particles at the surface escape as vapor from the surface.

A particle is a small localized object to which several physical or chemical properties, such as volume, density, or mass, can be assigned in the physical sciences.

Atoms are small units of matter that contain a number of particles known as subatomic particles. The term particle, on the other hand, refers to any small object.

As a result, the primary distinction between atoms and particles is that atoms are small units composed of multiple particles, whereas particles are minute portions of matter.

When a fluid is subjected to heat, the particles acquire energy and start moving extremely fast, causing the liquid to expand.

The much more energetic particles at the exterior getaway as vapor phase from the surface as the liquid warms.

Thus, the arrangement and movement of the particles gets disturbed when a substance is boiled, and it gets escaped as vapor.

The diagram that shows a pure substance which is composed of only individual atoms and not molecules will be: argon gas. Option D is correct.

A pure substance composed of only individual atoms is called an element. In the periodic table, each element is represented by a unique symbol, and its atoms cannot be further broken down into simpler substances by chemical means.

Liquid water: Water (H₂O) is a compound composed of two hydrogen atoms bonded to one oxygen atom. It consists of molecules, not individual atoms.

Hydrogen gas: Hydrogen gas (H₂) is composed of two hydrogen atoms bonded together to form a diatomic molecule. It is not composed of individual atoms.

Carbon dioxide GAS: Carbon dioxide (CO₂) is a compound consisting of one carbon atom bonded to two oxygen atoms, forming a molecule of CO₂.

Argon gas: Argon (Ar) is an element, and in its pure form as a gas, it exists as individual argon atoms (Ar). It is not bonded to any other atoms, and there are no molecules involved. Therefore, argon gas is composed of individual atoms and represents a pure substance.

Hence, D. is the correct option.

If the same index fossil is found in different areas, the strata in each area were likely deposited at the same time. Thus, the principle of faunal succession makes it possible to determine the relative age of unknown fossils and correlate fossil sites across large discontinuous areas.

Answer:

0.034 = 34×10^-3

Explanation:

This is because the special point is notated until it goes in front of the first counting number

Scientific notation is a way of expressing numbers that are very large or very small in a compact and standardized format. 0.034 in scientifc notation is written as 3.4 × 10⁻³

In scientific notation, a number is expressed as the product of a coefficient and a power of 10. The coefficient is a decimal number greater than or equal to 1 but less than 10, and the power of 10 represents the magnitude of the number. The power of 10 indicates the number of places the decimal point must be moved to obtain the original number.

For example:

The number 4,500,000 can be written in scientific notation as 4.5 x 10⁶, where the coefficient is 4.5 and the power of 10 is 6.

The number 0.000043 can be written in scientific notation as 4.3 x 10⁻⁵, where the coefficient is 4.3 and the power of 10 is -5.

Scientific notation allows for easy representation of very large or small numbers and simplifies calculations involving these numbers. It is particularly useful in scientific fields where values such as distances, masses, and concentrations can vary over a wide range.

Answer:

Answer: 8 protons and 8 neutrons

Explanation:

The mass number of oxygen is 16

Atomic number is 8

but proton number = atomic number = 8 protons

[tex]neutrons = mass \: number - atomic \: number \\ [/tex]

neutrons = 16 - 8 = 8 neutrons.

The nucleus of an atom of oxygen typically contains 8 protons and 8 neutrons specifically. So, none of the above options is correct.

The atomic number may be defined as the number of a chemical element in the periodic table through which the elements are arranged in order of increasing the number of protons in the nucleus.

The atomic number of an element = The number of protons in the nucleus of an atom.

Now, according to the question,

If Oxygen has an atomic number of 8, that means the number of protons = 8.

The number of neutrons can be calculated as follows:

Neutrons = mass number - the atomic number.

                = 16 - 8 = 8 neutrons.

Therefore, the nucleus of an atom of oxygen typically contains 8 protons and 8 neutrons specifically. So, none of the above options is correct.
