Front

What is Earth's energy budget?

Back

Earth's energy budget refers to the balance between the energy Earth receives from the sun and the energy it radiates back into space. It is crucial for determining our climate.

Front

What does a generator transform?

Back

A generator transforms mechanical energy into electrical energy.

Front

What is conduction?

Back

Conduction is the transfer of heat through direct contact between materials, such as a pot touching a flame.

Front

What is convection?

Back

Convection is the transfer of heat through the movement of fluids (liquids or gases), where warmer areas rise and cooler areas sink.

Front

What is radiation?

Back

Radiation is the transfer of energy through electromagnetic waves, such as heat from the sun.

Front

What is energy conversion?

Back

Energy conversion is the process of changing energy from one form to another, such as electrical energy to heat energy.

Front

What energy conversion occurs in a toaster?

Back

A toaster converts electrical energy into heat energy.

Front

What is an example of an object that converts light to electrical energy?

Back

A solar panel is an example of an object that converts light energy into electrical energy.

Front

What is the role of heat in boiling water?

Back

Heat energy is transferred to the water, causing its temperature to rise until it reaches boiling point.

Front

What is the difference between heat and temperature?

Back

Heat is the energy transferred between objects due to a temperature difference, while temperature is a measure of the average kinetic energy of particles in a substance.
