Question

The first law of thermodynamics is a statement of

• A. conservation of heat
• B. conservation of work
• C. conservation of momentum
• D. conservation of energy

Answer 1

The correct option is D

conservation of energy

The law of conservation of energy states that the total energy of an isolated system is conserved. The first law of thermodynamics restates this law in terms of heat added to a system the amount of work it does and the internal energy of the system in terms of its kinetic energy.
