Which option states the principle behind the law of conservation of mass and the law of conservation of energy?
a) energy and mass cannot be created or destroyed during physical changes or chemical reactions.
b) energy and mass are the properties that scientists measure when studying physical changes and chemical reactions.
c) an object's energy and mass have a direct relationship with that object's temperature.
d) an object's energy and mass have an indirect relationship with that object's temperature.

A

Explanation:

The law of conservation of mass states that matter can never be created nor destroyed but can be converted from one form to another.

The law of conservation of energy posits that energy cannot be created nor destroyed but can be converted from one form to another.

These laws are the basic laws of existence. Although the laws have been adjusted, they still form the basic principle behind several scientific laws and are responsible for a whole lot of scientific advancements.

While the first law focuses on matter and the content of matter in a body, the second law basically focuses on energy. The second law serves to support the inter convertibility behind the several forms or types of energy.

For example, to do many useful work at home, it is found that energy is converted from its electric form to say heat in an electric iron to press our clothes.

Also, the first law is a fundamental principle useful in the balancing of our chemical equations.

it is a solid
