Thermal Energy review

Front

What is thermal energy?

Back

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

Front

What is temperature?

Back

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

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 light.

Front

What happens to temperature during a phase change?

Back

During a phase change, the temperature of a substance stays the same while it changes state.

Front

What is thermal expansion?

Back

Thermal expansion is the increase in volume of a substance due to an increase in temperature.

Front

What is specific heat?

Back

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

Front

What is the difference between heat and temperature?

Back

Heat is the energy transferred between substances due to a temperature difference, while temperature is a measure of the average kinetic energy of particles.

Front

What is an example of conduction?

Back

An example of conduction is a metal spoon getting hot when placed in a hot soup.
