Thermal Equilibrium (7.8B)

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.

Front

What is conduction?

Back

Conduction is the transfer of thermal energy through direct contact between materials, where heat moves from the warmer object to the cooler one.

What is convection?

Back

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

What is radiation?

Back

Radiation is the transfer of thermal energy in the form of electromagnetic waves, such as infrared radiation, and does not require a medium to travel.

How does thermal energy move through a metal rod when one end is heated?

Back

Thermal energy moves through the rod primarily by conduction, as the heat travels from the hot end to the cooler end.

Front

What happens when ice is added to water?

Back

Heat transfers from the warmer water to the cooler ice, causing the ice to melt and the water temperature to decrease.

What is the role of thermal energy in cooling a hot object?

Back

Thermal energy moves from the hot object to the cooler surroundings until both reach thermal equilibrium.

What is the difference between conduction and convection?

Back

Conduction occurs through direct contact, while convection involves the movement of fluids to transfer heat.

Front

What is an example of radiation in everyday life?

Back

An example of radiation is feeling the warmth of the sun on your skin, even though you are not in direct contact with it.

Front

What is the significance of thermal equilibrium in a closed system?

Back

In a closed system, thermal equilibrium ensures that energy is evenly distributed, preventing temperature differences.
