a) Temperature is a measure of how hot or cold something is; specifically, a measure of the average kinetic energy of the particles in an object, which is a type of energy associated with motion. .

b) Radiation is energy that comes from a source and travels through space and may be able to penetrate various materials. Light, radio, and microwaves are types of radiation that are called nonionizing. ..

c) Thermal expansion is the tendency of matter to change in shape, volume, and area in response to a change in temperature. ... The degree of expansion divided by the change in temperature is called the material's coefficient of thermal expansion.
