Heat Transfer

Front

What is heat transfer?

Back

The process of thermal energy moving from one object or substance to another due to a temperature difference.

Front

What are the three main methods of heat transfer?

Back

Conduction, convection, and radiation.

Front

Define conduction.

Back

The transfer of heat through direct contact between materials.

Front

Define convection.

Back

The transfer of heat by the movement of fluids (liquids or gases) due to differences in density.

Front

Define radiation.

Back

The transfer of heat in the form of electromagnetic waves, such as infrared radiation.

Front

What is an example of conduction?

Back

Touching a hot stove and feeling the heat transfer to your hand.

Front

What is an example of convection?

Back

Boiling water where the hot water rises and cooler water sinks.

Front

What is an example of radiation?

Back

Feeling the warmth of the sun on your skin.

Front

What heats up faster, sand or water?

Back

Sand heats up faster than water due to its lower specific heat capacity.

Front

What is specific heat capacity?

Back

The amount of heat required to raise the temperature of a unit mass of a substance by one degree Celsius.
