Thermal Equilibrium

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 direction does heat energy transfer between two objects with different temperatures?

Back

Heat energy transfers from the object with a higher temperature to the object with a lower temperature.

Front

What is temperature a measure of?

Back

Temperature is a measure of the average kinetic energy of the molecules in a substance.

Front

How does heat transfer occur when holding a cold object?

Back

Heat transfers from your warm hand to the cold object, causing your hand to feel cold.

Front

What happens to the temperature when two substances at different temperatures are mixed?

Back

The final temperature will be between the two initial temperatures, depending on their masses and specific heat capacities.

Front

What is the effect of temperature on the volume of liquids?

Back

Most liquids expand when heated and contract when cooled.

Front

What happens to the liquid in a thermometer as temperature increases?

Back

The liquid in a thermometer expands as the temperature increases.

Front

What is conduction?

Back

Conduction is the transfer of heat through a material without the movement of the material itself, typically occurring in solids.

Front

What is convection?

Back

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

Front

What is radiation?

Back

Radiation is the transfer of heat in the form of electromagnetic waves, which can occur in a vacuum.
