Heat Energy Flashcard

Front

What is heat energy?

Back

Heat energy is the energy that comes from the temperature of matter. It is the energy that is transferred from one body or system to another due to a temperature difference.

How does heat move between objects?

Back

Heat moves from warmer areas to cooler areas until thermal equilibrium is reached.

Front

What is conduction?

Back

Conduction is the transfer of heat through a material without the movement of the material itself, typically occurring in solids.

Front

What is convection?

Back

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

Front

What is radiation?

Back

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

Front

What is an insulator?

Back

An insulator is a material that does not allow heat to move easily through it, such as rubber or glass.

Front

What is a conductor?

Back

A conductor is a material that allows heat to pass through it easily, such as metals like copper and aluminum.

Front

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 is the difference between kinetic and potential energy?

Back

Kinetic energy is the energy of motion, while potential energy is stored energy based on an object's position or state.

Front

What is thermal energy?

Back

Thermal energy is the total kinetic energy of all the particles in a substance.
