Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Energy cannot be made or destroyed, but simply changes form is
A
the 1st Law of Thermodynamics
B
the 2nd Law of Thermodynamics
C
the Law of Entropy
D
Law of Relativity
Explanation: 

Detailed explanation-1: -The first law of thermodynamics states that energy can neither be created nor destroyed, only altered in form. For any system, energy transfer is associated with mass crossing the control boundary, external work, or heat transfer across the boundary. These produce a change of stored energy within the control volume.

Detailed explanation-2: -The first law asserts that if heat is recognized as a form of energy, then the total energy of a system plus its surroundings is conserved; in other words, the total energy of the universe remains constant.

Detailed explanation-3: -The first law of thermodynamics is equivalent to the law of conservation of energy: energy cannot be created or destroyed; the total amount of energy in the Universe is fixed.

Detailed explanation-4: -The first law of thermodynamics, also known as the law of conservation of energy, states that energy can neither be created nor destroyed, but it can be changed from one form to another.

Detailed explanation-5: -1st Law of Thermodynamics-Energy cannot be created or destroyed. 2nd Law of Thermodynamics-For a spontaneous process, the entropy of the universe increases. 3rd Law of Thermodynamics-A perfect crystal at zero Kelvin has zero entropy.
