Answer:
The approximate change in entropy is -14.72 J/K.
Explanation:
Given that,
Temperature = 22°C
Internal energy [tex]U=4.30\times10^{3}\ J[/tex]
Final temperature = 16°C
We need to calculate the approximate change in entropy
Using formula of the entropy
[tex]\Delta S=\dfrac{\Delta U}{T}[/tex]
Where, [tex]\Delta U[/tex] = internal energy
T = average temperature
Put the value in to the formula
[tex]\Delta S=\dfrac{-4.30\times10^{3}}{\dfrac{22+273+16+273}{2}}[/tex]
[tex]\Delta S=-14.72\ J/K[/tex]
Hence, The approximate change in entropy is -14.72 J/K.
