Laws of Thermodynamics and Newton's Laws of Motion

Question 1

Zeroth Law of Thermodynamics

Answer 1

If system A and system B are in thermal equilibrium with system C, they are in thermal equilibrium with each other.

Question 2

First Law of Thermodynamics

Answer 2

The total energy of an isolated system is conserved. Energy may be converted from one form to another, but it cannot be created or destroyed.

Question 3

Second Law of Thermodynamics

Answer 3

The entropy of the universe is always greater than zero, and is always increasing.

Question 4

Third Law of Thermodynamics

Answer 4

The entropy of a perfect crystal is zero.

Question 5

Newton’s First Law of Motion

Answer 5

Every object persists in its state of rest or uniform motion in a straight line unless a force changes that state.

Question 6

Newton’s Second Law of Motion

Answer 6

F = ma.

Question 7

Newton’s Third Law of Motion

Answer 7

For every reaction, there is an equal and opposite reaction.

Question 8

Which of Newton’s Laws is also known as the “Law of Inertia”?

Answer 8

Newton’s First Law.
