ENS162 Midterm: Dynamics of Rigid Bodies Seatwork 3

Which physical law underlies the first law of thermodynamics?

1. The law of conservation of energy

2. The law of conservation of mass

3. The law of conservation of momentum

4. None of these

Choose the correct statement that supports the second law of thermodynamics.

1. The second law of thermodynamics is a principle that demonstrates the conservation of energy

2. The second law states that energy always degrades quality-wise

3. According to this, the entropy of an isolated system may decrease or increase

4. This law states that the flow of energy can take place in any direction naturally

The conservation of momentum is most closely related to

1. Newton’s first law

2. Newton's second law

3. Newton’s third law

4. Newton’s fourth law
