Explanation:
Relation between entropy change and specific heat is as follows.
The given data is as follows.
mass = 500 g, = 24.4 J/mol K
= 500 K,
= 250 K
Mass number of copper = 63.54 g /mol
Number of moles =
=
= 7.86 moles
Now, equating the entropy change for both the substances as follows.
=
= 750
So, =
- For the metal block A, change in entropy is as follows.
=
= -3.04 J/ K mol
- For the block B, change in entropy is as follows.
=
= 4.296 J/Kmol
And, total entropy change will be as follows.
= 4.296 + (-3.04)
= 1.256 J/Kmol
Thus, we can conclude that change in entropy of block A is -3.04 J/ K mol and change in entropy of block B is 4.296 J/Kmol.
