latent heat of sublimination of neon and change in entropy t

latent heat of sublimination of neon and change in entropy
thermal physics problem.

Solution

The latent heat of sublimation at triple point is (335+1803)J/mol=2138 J/mol.

Heat abosrbed to vaporize 1 mole of liquid neon is 1803 J. The temperature of the process is 24.57 K. So change in entropy is, 1803/24.57 J/K=73.38 J/K.
