Heat Transfer Practice Test

Front

What is conduction in heat transfer?

Back

Conduction is the process of heat transfer through direct contact between materials, where heat moves from the hotter object to the cooler one.

What is convection in heat transfer?

Back

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

Front

Provide an example of convection.

Back

Hot air rising and cooler air falling.

What process causes the metal handle of a pot to become hot when the pot is heated on a stove?

Back

Conduction causes the metal handle of the pot to become hot.

Front

What is the primary mechanism responsible for the uneven heating of air in the atmosphere?

Back

Convection is most responsible for the uneven heating of the air in the atmosphere.

How does temperature affect the rate of conduction?

Back

The greater the temperature difference between two objects, the faster the rate of conduction.

What role does density play in convection?

Back

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