Thermal Energy

Front

What is thermal energy?

Back

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

Front

What is conduction?

Back

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

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 from the sun.

Front

What is temperature?

Back

Temperature is a measure of how hot or cold an object is, indicating the average kinetic energy of its particles.

Front

What is a conductor?

Back

A conductor is a material that allows heat to flow through it easily, such as metals.

Front

What is an insulator?

Back

An insulator is a material that resists the flow of heat, such as rubber or wood.

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 an example of conduction?

Back

Heat moving from a clothes iron to a shirt is an example of conduction.

Front

What is an example of convection?

Back

Warm air rising and cool air sinking in a room is an example of convection.
