Heat Transfer

Front

What is heat transfer?

Back

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

Front

Define radiation.

Back

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

What happens to the temperature of water when an ice cube melts in it?

Back

The temperature of the water will be between 0°C and 28°C after the ice cube melts.

Front

What is the original source of most energy on Earth?

Back

Energy that reaches Earth’s surface by radiation from the Sun.

Front

Which material is a poor conductor of heat?

Back

Plastic is a poor conductor of heat.

Front

Give an example of heat transfer by conduction.

Back

An ice cube melting in a person’s hand is an example of conduction.
