Thermal Equilibrium

Front

What is thermal equilibrium?

Back

Thermal equilibrium is the state in which two objects in contact with each other reach the same temperature, resulting in no net heat transfer between them.

What is conduction?

Back

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

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.

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.

How does heat transfer occur between two objects?

Back

Heat transfer occurs from the hotter object to the cooler object until thermal equilibrium is reached.

What is the role of physical contact in conduction?

Back

For conduction to occur, two objects must be in physical contact with each other.

Front

What happens to the temperature of an object when it absorbs heat?

Back

When an object absorbs heat, its temperature increases as the kinetic energy of its molecules increases.

What is the direction of heat flow?

Back

Heat always flows from hot to cold objects.

Front

What is an example of conduction in everyday life?

Back

An example of conduction is when a metal spoon gets hot after being placed in a pot of boiling water.
