Question

Latent heat of fusion of a compound is 3000 J/mol at 27°C. Entropy change will​

Answer 1

Entropy Change is of 10 $\frac {J}{molK}$

Explanation:

• The Thermal System when becomes unavailable for the conversion to Mechanical Energy then it is being represented by Entropy (Which is a Thermal Quantity).

• The randomness in a system or degree of disorderliness can also interpret the entropy.

The Given temperature of 27°C is being converted to Kelvin.

We know that 1°C = 273 K

So,  

27°C = 273 + 27

= 300 K

$\Delta S_{system} = \frac {q_{rev}}{T} = \frac {3000}{300}$

= 10 $\frac {J}{molK}$
