Thermal Energy Midterm Study Guide

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 the relationship between kinetic energy and temperature?

Back

As the temperature of an object increases, the kinetic energy of its particles also increases.

Front

What is matter?

Back

Anything that takes up space and has mass is called matter.

Front

What happens to a liquid when enough energy is added?

Back

When enough energy is added to a liquid, it changes phase to a gas.

Front

What tool is used to measure temperature?

Back

A thermometer is used to measure temperature.

Front

How does heat transfer occur?

Back

Heat transfer occurs from a warmer object to a cooler object.

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).

Front

What is radiation?

Back

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