Thermal Energy Transfer

Front

What is thermal energy transfer?

Back

The process of heat moving from one object or substance to another.

Front

What are the three main methods of thermal energy transfer?

Back

Conduction, convection, and radiation.

Front

Why is brick a better material than metal for building a fireplace?

Back

Brick is heat resistant, allowing it to withstand high temperatures without deforming.

Front

What is conduction?

Back

The transfer of thermal energy through direct contact between materials.

Front

What is convection?

Back

The transfer of thermal energy through the movement of fluids (liquids or gases) due to differences in temperature.

Front

What is radiation in the context of thermal energy transfer?

Back

The transfer of thermal energy through electromagnetic waves, which can occur in a vacuum.

Front

What happens to warm air in convection heat transfer?

Back

Warm air rises while cold air sinks.

Front

What is the role of temperature difference in thermal energy transfer?

Back

Thermal energy naturally flows from areas of higher temperature to areas of lower temperature.

Front

What occurs to popcorn kernels when they are heated in a microwave?

Back

The kernels expand due to the buildup of steam inside them.

Front

Give an example of convection in everyday life.

Back

Boiling spaghetti noodles in water is an example of convection.
