Temperature is the average kinetic energy of gas molecules.

What is absolute zero?

The term absolute zero refers to the hypothetical point where the energy of molecules is zero. It is the point where all of their motion stops completely.

In a liquid, the movement of the molecules is more significant than in a solid. If you keep increasing the temperature of a liquid, it will boil and become a gas.

Matter contains energy which depends on the temperature of matter. To remove the energy of matter, you have to lowering its temperature.

The addition of energy to matter occurs when matter is heated. Hence, you add energy to matter by heating it.

The molecules at warm temperatures differ from the molecules at cool temperatures because the molecules at warmer temperatures move around more.

The air on a hot day compares to the air on a cool day in the sense that on a hot day, air molecules have more energy.

Temperature is depends on the kinetic energy of molecules. Hence, the best description of temperature is motion of molecules.

The temperature of a body is the average kinetic energy of its molecules.  When two things that are not touching have the same temperature their molecules move at the same average speed.

Since a liquid receives energy when it is heated, when the liquid is boiled beyond its boiling point, It will become a gas.

The difference between heat and temperature is that temperature measures the motion of molecules, and heat is the energy of that motion.
