Thermal Energy and Heat Transfer

Front

What is conduction in the context of heat transfer?

Back

Conduction is the transfer of heat through direct contact between materials.

Front

What is radiation in the context of heat transfer?

Back

Radiation is the transfer of heat in the form of electromagnetic waves.

Front

Provide an example of conduction.

Back

Touching a hot stove.

Front

Provide an example of radiation.

Back

The Sun heating the Earth.

Front

What is convection in the context of heat transfer?

Back

Convection is the transfer of heat through the movement of fluids (liquids or gases).

Front

How does heat transfer from a hot object to a cooler object?

Back

Heat transfers from the hot object to the cooler object until thermal equilibrium is reached.

Front

What is thermal equilibrium?

Back

Thermal equilibrium is the state in which two objects in contact do not exchange heat, meaning they are at the same temperature.

Front

What role does temperature play in heat transfer?

Back

Temperature determines the direction of heat transfer; heat flows from higher to lower temperature.

Front

What is the difference between heat and temperature?

Back

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

Front

What is an insulator?

Back

An insulator is a material that resists the flow of heat.
