Thermal Energy Unit Study Guide

Front

What factors affect the temperature change of a substance?

Back

The chemical composition of the substance, the mass of the substance, and the amount of heat added to or removed from the substance.

Front

How is heat generated when rubbing hands together?

Back

Friction transforms mechanical energy into thermal energy.

Front

How does the mass of a substance affect its temperature change?

Back

A sample with greater mass will change temperature slower than a sample with less mass.

Back

A process where a substance transforms into a different substance, such as burning or digestion.

Front

What is an example of a physical change?

Back

Boiling water to create steam is a physical change.

Front

What is thermal energy?

Back

Thermal energy is the energy that comes from the temperature of matter.

Front

What is the relationship between heat and temperature?

Back

Heat is the energy transferred between substances due to a temperature difference.

Front

What happens to the temperature of a substance when heat is added?

Back

The temperature of the substance increases.
