how can you use terms such as thermal energy, particles, motion, and flow to explain the movement of heat in our world
Answer: Thermal energy is the kinetic energy of particles and heat is the term used to describe how this energy may flow to other systems, such as in a radiator.
Explanation: Molecules have a level of kinetic energy that can be measured by temperature. Higher temperatures result in more rapid and frequent collisons of particles in motion. Heat is the term used to measure the quantity of vibration energy in a given system. The SI unit for heat energy is the Joule. The water molecules in a pot of boiling water have a kinetic energy sufficient for them to break away from other water molecules and become gaseous (boiling point). The heat energy in 1 liter of water at 95C can be calculated in terms of Joules/liter, based on the specific heat of water (e.g., in units of J/gC). This heat can flow to other systems. A home boiler heater unit heats water tha can be pumped around the house ehre it will flow from radiators into thje surrounding air.
Heat is the word used to explain how this energy may transfer to other systems, such as in a radiator, and thermal energy is the kinetic energy of particles.
What is thermal energy?
By virtue of its temperature, a system in a condition of thermodynamic equilibrium has thermal energy or internal energy. Unlike the energy of systems that are not in a state of thermodynamic equilibrium, thermal energy cannot be transformed into meaningful work as quickly.
For instance, the same fluid or solid in a thermodynamic equilibrium state with the same energy (as thermal energy) cannot do work unless it is combined with another substance at a different temperature, as in a heat engine. However, the same fluid or solid in a moving state with the same energy (as mechanical energy) can be converted to work in some mechanical device, such as a windmill or a waterwheel.
Therefore, heat is the word used to explain how this energy may transfer to other systems, such as in a radiator, and thermal energy is the kinetic energy of particles.

Answer:
Bailee is incorrect. The mass of objects stay the same but the weight will change.
Explanation:
Mass is how much space something takes up, so that wouldn't change on the moon. The weight however would change because the gravitational pull on the earth is different from that on the moon.
I hope this helps!
Bailee explained that when traveling to the moon. The statement of Bailee is incorrect. The mass of the objects stays the same, but the weight will change. The correct option is B.
What is gravity?Gravity is a force that pulls all objects towards itself. It is present on the earth and in the galaxy. Gravity is the cause of all planets, and the sun and the moon stay in their own places.
The weight of items on the moon is equal to their weight on Earth, according to Bailee, thus he needs only bring a small amount of luggage. The mass is the quantity of matter. The mass never changes, only the weight changes of an object when they are on different planets.
Thus, the correct option is B. The mass of the objects stays the same, but the weight will change.

Which of the following is more soluble in water, methanol (CH3OH), or CH2I2(l).
Answer:
CH3OH
Explanation:
has hydroxide ions
Solubility has been the property of the substance to get dissolved to form the solution. Methanol (CH₃OH) is more soluble in water than Diiodomethane (CH₂I₂).
What is solubility?Solubility is best defined as the capability of the substance to get dissolved or dissociated into a solvent for the formation of the solution at a given temperature. The solubility of the various substances varies and is an important part of the mixture and solution.
Solubility in water has been the measure of the solute to get dissolved in water. The pressure and the temperature of the system directly affect the solubility of any substance in a solvent. Water is a polar molecule with hydrogen bonds in a great solvent that dissolves almost all the molecules like salt, sugar, etc.
Methanol is soluble in water as it contains hydrogen bonds as the intermolecular forces that interact with the polar water molecule by the virtue of the hydroxide and the hydrogen ions that show the molecular attraction and allows the molecule to get dissolved.
Therefore, methanol is soluble in water.

An ion is formed by either
Explanation:
By definition, an ion is an electrically charged particle produced by either removing electrons from a neutral atom to give a positive ion or adding electrons to a neutral atom to give a negative ion. When an ion is formed, the number of protons does not change.
Answer:
Ions are formed by the addition of electrons to, or the removal of electrons from, neutral atoms or molecules or other ions.
Explanation:
by combination of ions with other particles; or by rupture of a covalent bond between two atoms in such a way that both of the electrons of the bond are left in association with one of the formerly bonded atoms. Examples of these processes include the reaction of a sodium atom with a chlorine atom to form a sodium cation and a chloride anion; the addition of a hydrogen cation to an ammonia molecule to form an ammonium cation; and the dissociation of a water molecule to form a hydrogen cation and a hydroxide anion.

What is the voltage for the equation CuCl2+Zn—> ZnCl2+Cu?
The standard voltage for the equation CuCl₂ + Zn —> ZnCl₂ + Cu is -1.1 Vol.
What is voltage?
Voltage is the pressure of the charged electrons in an electric circuit which pushes the electrons towards the switch, which makes the light illuminate. By Ohm's law, voltage is equal to current x resistance.
V = IR
The reaction is CuCl₂ + Zn —> ZnCl₂ + Cu, which means it is a dry cell battery, where the anode, zinc reacts with chloride that is the cathode. In the dry battery cell, the chemical energy is stored in it, which converts into electrical energy.
The voltage will be minimum, which is -1.1. The liquid battery cells or the electric fittings in our house contain high voltages because it gets direct current, but dry battery cells contain minimum amount of voltage and it is used to operate small objects.
Thus, the standard voltage will be -1.1 Vol.
