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, meaning they are at the same temperature.

Front

What happens to heat when ice is placed in water?

Back

The heat from the water moves into the ice, causing the water to cool down.

Front

How does heat transfer occur between two objects of different temperatures?

Back

Heat transfers from the warmer object to the cooler object until they reach thermal equilibrium.

Front

What is conduction?

Back

Conduction is the transfer of thermal energy through direct contact between materials.

Front

What is convection?

Back

Convection is the transfer of thermal energy through the movement of fluids (liquids or gases) caused by differences in temperature.

Front

What is radiation?

Back

Radiation is the transfer of thermal energy through electromagnetic waves, which can occur in a vacuum.

Front

Give an example of conduction in everyday life.

Back

Ironing a shirt is an example of conduction, where heat is transferred from the iron to the fabric.

Front

What is an example of convection?

Back

Boiling water is an example of convection, where hot water rises and cooler water sinks, creating a circular motion.

Front

How does heat transfer when you step on a cold tile floor after a hot shower?

Back

Heat from your feet is transferred to the cold tile floor.

Front

What is the direction of heat transfer?

Back

Heat always transfers from a warmer object to a cooler object.
