Revision Monkey - Energy Stores and Transfers

What is chemical energy stored in?

• Moving objects

• Hot objects

• Stretched springs

• Food and fuels

Which type of energy store increases when an object is heated?

• Kinetic energy

• Elastic potential energy

• Thermal energy

• Gravitational potential energy

What happens to the gravitational potential energy of an object as it is raised higher above the ground?

• It is converted to kinetic energy

• It increases

• It remains the same

• It decreases

What is the law of conservation of energy?

• Energy can be created but not destroyed

• Energy can neither be created nor destroyed

• Energy is always lost when transferred between stores

• Energy can be destroyed but not created

Which of the following is an example of wasted energy?

• Chemical energy in food

• Heat energy from electrical equipment

• Kinetic energy in moving objects

• Gravitational potential energy in raised objects

How can energy be transferred between different energy stores?

• It cannot be transferred

• Through electrical, mechanical, sound, and light means

• Only through heat

• Only through mechanical means

What happens to most wasted energy?

• It is used to do work

• It is converted into chemical energy

• It is stored in the thermal energy store of the surroundings

• It disappears
