Heat Transfer in a Reversible Process
Reversible processes are those which can be reversed without leaving any trace on the surroundings. The heat transfer in a reversible process from state 1 to state 2 is given by:
Q for reversible = (To) * (S2 - S1)
Explanation:
- Q for reversible: It represents the heat transfer in a reversible process.
- To: It represents the temperature of the surroundings.
- S2 and S1: They represent the entropy of the system at state 2 and state 1 respectively.
The heat transfer in a reversible process is given by the formula above because of the following reasons:
- Reversible processes are those which can be reversed without leaving any trace on the surroundings. Hence, these processes are ideal and do not have any losses of energy.
- The formula for heat transfer in a reversible process is derived from the second law of thermodynamics, which states that the entropy of the universe always increases in an irreversible process and remains constant in a reversible process.
- The formula for heat transfer in a reversible process shows that the heat transfer is proportional to the difference in entropy between the initial and final states of the system. This means that the greater the difference in entropy, the greater the heat transfer.
Conclusion:
The correct option for the heat transfer in a reversible process from state 1 to state 2 is option B, which is given by:
Q for reversible = (To) * (S2 - S1)
This formula is derived from the second law of thermodynamics and shows that the heat transfer is proportional to the difference in entropy between the initial and final states of the system.
