The __________ of a substance is a characteristic property and can be used to identify a substance.

• thermal energy

• Kinetic Energy

• thermal expansion

• temperature

• bimetallic

Which statement best describes what happens when particles gain kinetic energy?

• When particles in a solid, liquid, or gas gain kinetic energy, thermal contraction occurs when the particles move close together and the volume of the substance decreases.

• When particles in a solid, liquid, or gas gain kinetic energy, thermal expansion occurs as the particles move faster, farther apart, and the volume of the substance increases.
