Explanation:
The first law of thermodynamics, also known as the law of energy conservation, states that in a closed system undergoing a cycle, the net work delivered to the surroundings is proportional to the net heat taken from the surroundings.
- The first law of thermodynamics is a fundamental principle in physics and it applies to all systems, from the microscopic level to the macroscopic level.
- The law states that energy cannot be created or destroyed, only transferred or converted from one form to another.
- In the context of thermodynamics, a closed system refers to a system that does not exchange matter with its surroundings, but can exchange energy in the form of heat and work.
- A cycle refers to a series of processes that bring a system back to its initial state.
- According to the first law of thermodynamics, the net work done on or by a closed system during a cycle is equal to the net heat transferred into or out of the system.
- If the net work done on the system is positive, then the system is doing work on the surroundings. If the net work done on the system is negative, then the surroundings are doing work on the system.
- Similarly, if the net heat transferred into the system is positive, then heat is being added to the system. If the net heat transferred into the system is negative, then heat is being removed from the system.
- The first law of thermodynamics can be expressed mathematically as:
ΔU = Q - W
where ΔU is the change in internal energy of the system, Q is the net heat transferred into the system, and W is the net work done on the system.
- Since the internal energy of a closed system undergoing a cycle is constant (ΔU = 0), the first law of thermodynamics can be simplified to:
Q = W
This means that the net work done on or by the system during a cycle is equal to the net heat transferred into or out of the system.
- Therefore, option B is the correct answer as it accurately represents the first law of thermodynamics.
