Assertion : There is a natural asymmetry between converting work to heat and converting heat to work. Reason : No process is possible in which the sole result is the absorption of heat from a reservoir and its complete conversion into work.
1 Both Assertion and Reason are correct and Reason is the correct explanation of the Assertion.
2 Both Assertion and Reason are correct but Reason is not the correct explanation of the Assertion.
3 Assertion is correct but Reason is incorrect.
4 Assertion is incorrect but Reason is correct.
Explanation:
Both assertion and reason are correct and reason is the correct explanation of the assertion. Second law of thermodynamics states that total heat can never be converted into equivalent amount of work. Thus, option (1) is correct.

A piece of ice kept at room temperature melts on its own. State the law which satisfies the above statement.
1 Zeroth law of thermodynamics
2 First law of thermodynamics
3 Second law of thermodynamics
4 Third law of thermodynamics
Explanation:
The randomness increases when the ice changes into water at room temperature. Entropy also increases according to the second law of thermodynamics.

According to second law of thermodynamics, a process (reaction) is spontaneous, if during the process
When a spontaneous (naturally occurring) process takes place, it is accompanied by increase in entropy, i.e.\(\Delta {{\rm{S}}_{{\rm{universe }}}} = \Delta {{\rm{S}}_{{\rm{system }}}} + \Delta {{\rm{S}}_{{\rm{surroundings }}}} > 0\)

Assertion : The entropy of the universe is continuously increasing. Reason : All naturally occurring processes are accompanied by increase in entropy.
1 Both Assertion and Reason are correct and Reason is the correct explanation of the Assertion.
2 Both Assertion and Reason are correct but Reason is not the correct explanation of the Assertion.
3 Assertion is correct but Reason is incorrect.
4 Assertion is incorrect but Reason is correct.
Explanation:
The second law of thermodynamics asserts that the entropy of the universe consistently increases, signifying a natural tendency for systems to evolve towards greater disorder and randomness over time. So, option (1) is correct.
