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.

What is the principle of heat transfer?

Back

Heat transfer occurs from a warmer object to a cooler object until thermal equilibrium is reached.

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 infrared radiation.

How does temperature affect the rate of diffusion?

Back

Higher temperatures increase the rate of diffusion because particles move faster.

What is the formula for calculating the equilibrium temperature of two objects?

Back

(m1 * T1 + m2 * T2) / (m1 + m2), where m is mass and T is temperature.
