Thermal Equilibrium

Front

What is thermal equilibrium?

Back

Thermal equilibrium is the state in which two objects in thermal contact no longer transfer heat to each other, meaning they have reached the same temperature.

Front

What happens when two objects at different temperatures are in contact?

Back

They will exchange heat until they reach thermal equilibrium, where both objects have the same final temperature.

Front

What is the direction of heat transfer between two objects?

Back

Heat always transfers from the hotter object to the cooler object.

Front

What occurs when ice is placed in warm water?

Back

The heat from the warm water transfers to the ice, causing the water to cool down and the ice to melt.

Front

What is the effect of adding ice cubes to a drink?

Back

The heat from the drink transfers to the ice cubes, lowering the temperature of the drink.

Front

How does temperature relate to heat transfer?

Back

Heat transfer occurs from areas of higher temperature to areas of lower temperature until thermal equilibrium is reached.

Front

What does it mean if an object feels cold to the touch?

Back

It means that heat is being transferred from your skin to the object, making it feel cold.

Front

What is the role of thermal contact in heat transfer?

Back

Thermal contact allows for the transfer of heat between two objects, facilitating the process of reaching thermal equilibrium.

Front

What happens to the temperature of a hot object when it is placed in a cooler environment?

Back

The temperature of the hot object decreases as it loses heat to the cooler environment.

Front

What is an example of thermal equilibrium in everyday life?

Back

A cup of hot coffee cooling down to room temperature is an example of thermal equilibrium.
