Energy Transformations and Types

Front

What is energy transformation?

Back

Energy transformation is the process of changing energy from one form to another, such as converting chemical energy in food into kinetic energy when we move.

Front

What is stored chemical energy?

Back

Stored chemical energy is the energy held in the bonds of chemical compounds, like batteries, food, and fossil fuels, which can be released during chemical reactions.

Front

Which of the following is NOT a source of stored chemical energy? a) a battery in a toy car b) food c) the nucleus of an atom d) fossil fuels

Back

c) the nucleus of an atom.

Front

What is potential energy?

Back

Potential energy is the energy stored in an object due to its position or state, such as a compressed spring or a raised weight.

Front

What is chemical energy?

Back

Chemical energy is a form of potential energy stored in the bonds of chemical compounds, which can be released during a chemical reaction.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of an object in motion, which depends on its mass and velocity.

Front

What is thermal energy?

Back

Thermal energy is the total kinetic energy of particles in a substance, related to its temperature.

Front

In which direction does heat move?

Back

Heat moves from warmer areas to cooler areas.

Front

What is the difference between energy transformation and energy conversion?

Back

Energy transformation and energy conversion are often used interchangeably to describe the process of changing energy from one form to another.

Front

What is an example of energy transformation in everyday life?

Back

An example is a toaster converting electrical energy into thermal energy to toast bread.
