Energy Transformation and Conservation Quiz

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

The change of energy from one form to another.

Electrical Energy is converted into heat energy (thermal energy).

Oil stores chemical potential energy originally from sunlight, transforming it into chemical energy through photosynthesis and then animal consumption.

Fireworks transform stored chemical energy into light, sound, and heat energy upon ignition.

Food contains chemical potential energy that is transformed into thermal, mechanical, or other forms of energy when consumed, digested, and utilized by the body.

Electrical energy converts into thermal, light and sound energy, all are in use at once.

The total amount of energy in a system remains constant; energy can only be transformed from one form to another, it cannot be created or destroyed.

The process of changing energy from one form to another.

Thermal energy spreading out and becoming harder to use.

Turning thermal energy into other types of energy.

Energy released as heat during a transformation.

Energy that is dispersed and hard to harness after transformation.

Different forms of energy found in the universe, including chemical potential energy, thermal energy, light and sound energy, among others.

A measure of how effectively energy is used in a process or device, usually expressed as a ratio of useful energy produced to total energy absorbed.

The change of energy from one form to another, like chemical energy to mechanical energy.

The percentage of input energy that is converted into useful output energy (like motion).

An appliance that uses less energy to produce the same result compared to older models.

Energy cannot be created or destroyed, only transformed or transferred.

Reducing or saving energy consumption.

A 70% thermal loss in an engine means only 30% of converted energy is useful, making it less efficient.
