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 and no heat flows between them.

Front

What happens to the temperature of objects in thermal contact over time?

Back

The temperatures of the objects will equalize until they reach thermal equilibrium.

Front

What is the direction of heat transfer between two objects with different temperatures?

Back

Heat transfers from the hotter object to the cooler object.

Front

What is the role of insulation in maintaining thermal energy?

Back

Insulation reduces heat transfer, helping to maintain the thermal energy inside a space.

Front

How does thermal energy move in a well-insulated house on a hot day?

Back

Thermal energy moves from warmer rooms to cooler rooms until thermal equilibrium is reached.

Front

What happens to the temperature of a cold object placed in a warmer environment?

Back

The temperature of the cold object will increase until it matches the temperature of the surrounding environment.

Front

What is the effect of particle motion on temperature?

Back

An increase in particle motion typically results in an increase in temperature.

Front

What occurs when two objects at different temperatures are placed in contact?

Back

Energy transfers from the hotter object to the cooler object until they reach the same temperature.

Front

What is the significance of a temperature gradient?

Back

A temperature gradient indicates the direction of heat transfer, from higher to lower temperature.

Front

What happens to the thermal energy of a glass of cold water over time?

Back

The thermal energy of the cold water will increase until it matches the temperature of the surrounding environment.
