Answer:
The approximate change in entropy is -14.72 J/K.
Explanation:
Given that,
Temperature = 22°C
Internal energy
Final temperature = 16°C
We need to calculate the approximate change in entropy
Using formula of the entropy
Where, = internal energy
T = average temperature
Put the value in to the formula
Hence, The approximate change in entropy is -14.72 J/K.
