Answer:
The partial pressure of bar.
Explanation:
Given:
Volume L
Total pressure bar
Temperature of system K
Moles of nitrogen mole
Partial pressure bar
From ideal gas equation,
Where = gas constant
First finding partial pressure of nitrogen
bar
We know, total pressure is given by
bar
Therefore, the partial pressure of bar.

Explanation:
The relation between change in entropy and is as follows.
The given data is as follows.
mass = 500 g
= 24.4 J/mol K
= 500 K
= 250K
As, atomic mass of copper = 63.54 g /mol. Therefore, number of moles of copper will be calculated as follows.
Number of moles =
=
= 7.86 moles
Hence,
= 750
For the metal block A,
=
= -3.04 J/ K mol
For the block B,
= 4.296
Therefore, calculate the change in entropy as follows.
Total entropy change = 4.296 + (-3.04)
= 1.256 J/Kmol
Thus, we can conclude that the change in entropy for given two blocks of copper is 1.256 J/Kmol
