Unit 2 Thermal Energy Post-Test Review

Front

What is thermal energy?

Back

Thermal energy is the total kinetic energy of the particles in a substance, which determines its temperature.

Front

What is conduction?

Back

Conduction is the transfer of heat through direct contact between materials.

Front

What is convection?

Back

Convection is the transfer of heat through the movement of fluids (liquids or gases) caused by differences in temperature.

Front

What is radiation?

Back

Radiation is the transfer of heat in the form of electromagnetic waves, such as sunlight.

Front

What is insulation?

Back

Insulation is a material that reduces the transfer of heat between two areas.

Front

What happens to particles during melting?

Back

Particles gain energy and move further apart during melting.

Front

What is the purpose of a thermometer?

Back

A thermometer is used to measure the temperature of a substance.

Front

How does color affect heat absorption?

Back

Darker colors absorb more heat than lighter colors.

Front

What is the effect of thickness on insulation?

Back

Thicker insulation materials generally provide better thermal resistance.

Front

What is the significance of specific heat capacity?

Back

Specific heat capacity is the amount of heat required to raise the temperature of a unit mass of a substance by one degree Celsius.
