Front

Define conduction in the context of heat transfer.

Back

The transfer of heat from one particle of matter to another within an object or between two objects through direct contact.

Front

What is convection?

Back

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

Explain how convection works in heating soup on the stove.

Back

As the soup at the bottom heats up, it becomes less dense and rises, while cooler, denser soup descends, creating a circulation pattern.

What is radiation in terms of heat transfer?

Back

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

Front

How does heat flow between two objects in contact?

Back

Heat flows from the hotter object to the cooler object until thermal equilibrium is reached.

Front

What is thermal equilibrium?

Back

A state in which two objects in contact reach the same temperature and no heat flows between them.

Describe an example of conduction in everyday life.

Back

Touching a metal spoon that has been sitting in a hot pot of soup; the heat from the soup is conducted to the spoon.

What role does density play in convection?

Back

In convection, warmer, less dense fluid rises while cooler, denser fluid sinks, creating a circulation pattern.
