Amplify Thermal Energy Test Review

What is thermal equilibrium?

Back

Thermal equilibrium is the state in which two objects in contact with each other reach the same temperature and no heat flows between them.

Front

What happens to thermal energy when two objects at different temperatures come into contact?

Back

Heat flows from the hotter object to the cooler object until they reach thermal equilibrium.

Front

What is the relationship between temperature and thermal energy?

Back

Temperature is a measure of the average kinetic energy of particles in a substance, but it does not directly indicate the total thermal energy, which also depends on the mass and specific heat of the substance.

Front

What is the specific heat capacity?

Back

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

Front

How does mass affect thermal energy?

Back

The greater the mass of a substance, the more thermal energy it can store at a given temperature.

Front

What is heat transfer?

Back

Heat transfer is the movement of thermal energy from one object or substance to another due to a temperature difference.

Front

What are the three methods of heat transfer?

Back

The three methods of heat transfer are conduction, convection, and radiation.

Front

What is conduction?

Back

Conduction is the transfer of heat through direct contact between materials, where heat moves from the hotter part to the cooler part.

Front

What is convection?

Back

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

Front

What is radiation?

Back

Radiation is the transfer of heat in the form of electromagnetic waves, such as infrared radiation, and does not require a medium.
