Thermal Equilibrium

Front

What is thermal equilibrium?

Back

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

Front

How does heat transfer occur between two objects?

Back

Heat transfer occurs from the object with a higher temperature to the object with a lower temperature.

Front

What is conduction?

Back

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

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, and does not require a medium.

Front

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

Back

The temperature of the object increases when it absorbs heat.

Front

What is the role of thermal energy in heat transfer?

Back

Thermal energy is the total kinetic energy of particles in a substance, and it drives the heat transfer process.

Front

What is the significance of the phrase 'hot to cold' in heat transfer?

Back

It indicates the direction of heat flow, which always moves from areas of higher temperature to areas of lower temperature.

Front

Can heat transfer occur in a vacuum?

Back

Yes, heat transfer can occur in a vacuum through radiation.

Front

What is an example of conduction in everyday life?

Back

An example of conduction is touching a hot stove and feeling the heat transfer to your hand.
