Heat Transfer

Front

What is heat transfer?

Back

The movement of thermal energy from one object or substance to another.

Front

What are the three main types of heat transfer?

Back

Conduction, Convection, and Radiation.

Front

What is conduction?

Back

The transfer of heat through direct contact between materials.

Front

What is convection?

Back

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

Front

What is radiation?

Back

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

Front

How does conduction occur in metals?

Back

Metals conduct heat well because their atoms are closely packed, allowing energy to transfer quickly.

Front

What is an example of convection in everyday life?

Back

Warm air rising in a house or boiling water.

Front

What is the relationship between temperature and molecular motion?

Back

Temperature is a measure of the average kinetic energy of the molecules in a substance.

Front

How does heat from the Sun reach the Earth?

Back

Through radiation, as it travels through the vacuum of space.

Front

What happens to the density of a fluid when it is heated?

Back

It decreases, causing the warmer fluid to rise.
