​ Law Of Conservation Of Energy

​The law of conservation of energy states that energy can neither be created nor destroyed only converted from one form of energy to another. This means that a system always has the same amount of energy, unless it's added from the outside.

Multiple Choice

The Law Of Conservation Of Energy States

• Energy can be created or destroyed but not transformed

• Energy cannot be created or destroyed it can only be transformed.

• Energy cannot be created or destroyed

Multiple Choice

According to the Law of Conservation of energy, the amount of energy before and after a reaction must be the same. Which statement below is true?

• The total amount of energy is conserved

• The total amount of energy is less after a reaction

• The total amount of energy is more after a reaction

Multiple Choice

The law of conservation of energy states that energy cannot be created nor destroyed it can only change form or be transferred? Which of the following supports the law of conservation of energy found in all living systems?

• Decomposers transfer energy stored in the molecules of the dead organism to create new biomass for other organisms to feed on.

• Most plants and animals begin their life cycle with small energy needs and gain more requirements as they develop.

• The total mass of dead organism equals the total mass of matter released to the environment by decomposition.

• The total energy of all organisms is an ecosystem remains the same over time

Energy Transformations

​Energy transformation is when energy changes from one form to another – like in a hydroelectric dam that transforms the kinetic energy of water into electrical energy. While energy can be transferred or transformed, the total amount of energy does not change this is called energy conservation.
