Thermal Equilibrium

Front

What is thermal equilibrium?

Back

Thermal equilibrium is the condition where two substances in physical contact with each other exchange no heat energy, meaning they are at the same temperature.

Front

What happens when heating continues?

Back

Heating will continue until thermal equilibrium is reached.

Front

What is the relationship between heat gained and heat lost in a closed system?

Back

In a closed system with no heat losses, the heat gained by the cold water is equal to the heat lost by the hot water.

Front

If two objects A and B are in thermal equilibrium with a third object C, what can be said about A and B?

Back

A and B have the same temperature.

Front

What occurs when ice cubes are added to a glass of soda?

Back

The heat transfers from the soda (coke) to the ice.

Front

Define thermal energy.

Back

Thermal energy is the total kinetic energy of the particles in a substance, which is related to its temperature.

Front

What is the principle of energy transfer?

Back

Energy transfer occurs when heat moves from a warmer object to a cooler object until thermal equilibrium is reached.

Front

What is the significance of temperature in thermal equilibrium?

Back

Temperature is a measure of the average kinetic energy of particles; in thermal equilibrium, two objects have the same temperature.

Front

What is the effect of heat loss in thermal systems?

Back

Heat loss can prevent a system from reaching thermal equilibrium, leading to temperature differences.

Front

What is the concept of heat capacity?

Back

Heat capacity is the amount of heat energy required to change the temperature of a substance by one degree Celsius.
