Energy Transformations Practice

Front

What type of energy is present in a pot of hot water?

Back

Thermal energy is the energy that comes from the temperature of matter. In a pot of hot water, the water molecules move faster, indicating higher thermal energy.

Front

What type of energy does a battery convert to power devices?

Back

A battery converts chemical energy into electrical energy, allowing it to power devices.

Front

What is the energy stored in the bonds between atoms called?

Back

Chemical energy is the energy stored in the bonds of chemical compounds, like atoms and molecules.

Front

When a microwave oven operates, what type of energy is NOT transformed?

Back

Solar energy is not transformed by a microwave oven; it transforms electrical energy into thermal and light energy.

Front

What type of energy is stored in batteries?

Back

Batteries store chemical energy, which is converted to electrical energy when used.

Front

Define potential energy.

Back

Potential energy is the energy stored in an object due to its position or state. For example, a book on a shelf has potential energy due to its height.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of an object in motion. The faster an object moves, the more kinetic energy it has.

Front

Explain the transformation of energy in a light bulb.

Back

In a light bulb, electrical energy is transformed into light energy and thermal energy.

Front

What is mechanical energy?

Back

Mechanical energy is the sum of potential and kinetic energy in an object that is used to do work.

Front

What is the difference between thermal energy and heat?

Back

Thermal energy is the total energy of all the particles in an object, while heat is the transfer of thermal energy from one object to another.
