300 kJ of heat is supplied at constant temperature of 500 K, to a heat engine. The heat rejection takes place at 300 K. The following result are obtained (a) 210 kJ (b) 180 kJ (c) 150 kJ. Identify whether result is a reversible cycle. Irreversible cycle or impossible cycle respectively

  • a)
    reversible / irreversible / impossible respectively

  • b)
    irreversible / reversible / impossible respectively

  • c)
    irreversible / impossible / reversible respectively.

  • d)
    None of the above

Correct answer is option 'B'. Can you explain this answer?

To determine the change in entropy, we need to know the specific heat capacity of the substance in question. The formula for calculating the change in entropy is:

ΔS = Q / T

Where:
ΔS = change in entropy
Q = heat supplied
T = temperature

Assuming the specific heat capacity of the substance is constant and equal to c, we can rearrange the formula to solve for the change in entropy:

ΔS = Q / T = (300 kJ/s) / (290 K) = 1.034 kJ/(K*s)
