Front

What is the primary source of radiant energy on Earth?

Back

The Sun.

Front

How does heat transfer occur through radiation?

Back

Through the emission of electromagnetic waves.

Front

What is convection?

Back

Transfer of heat through the movement of currents in a liquid or gas.

Front

Can you give an example of convection?

Back

A pot of water boiling on a stove.

Front

What is conduction?

Back

Transfer of heat through direct contact between materials.

What is the difference between conduction and convection?

Back

Conduction occurs through direct contact, while convection involves the movement of fluids.

Front

What is thermal energy?

Back

The total kinetic energy of particles in a substance.

Front

What is the role of the Sun in energy transformation?

Back

The Sun provides radiant energy that is transformed into other forms of energy on Earth.

Front

What is an example of energy transformation in a solar panel?

Back

Radiant energy from the Sun is transformed into electrical energy.

Front

What is the principle of conservation of energy?

Back

Energy cannot be created or destroyed, only transformed from one form to another.
