Heat and Thermal Energy

Front

What is thermal energy?

Back

Thermal energy is the total kinetic and potential energy of all particles in an object.

Front

What is heat?

Back

Heat is the energy that is transferred from a warmer object to a cooler object.

Front

What does temperature measure?

Back

Temperature is a measure of the average kinetic energy of the particles in a substance.

Front

What type of heat transfer occurs when a lizard warms up under a lamp?

Back

This is an example of radiation.

Front

Is thermal energy always conserved within a system?

Back

Yes, thermal energy is always conserved within a system.

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 light.

Front

What is the difference between kinetic energy and potential energy?

Back

Kinetic energy is the energy of motion, while potential energy is stored energy based on position.

Front

What happens to thermal energy when ice melts?

Back

Thermal energy is absorbed by the ice, causing it to change from solid to liquid.
