One mole of an ideal gas for which C(V)=...

One mole of an ideal gas for which `C_(V)= 3//2R` heated at a constant pressure of 1 atm from `25^(0)C "to" 100^(0)C`
What will be the amount of work done in the process?

A

`-62.32` Cal

B

`-140.925` Cal

C

`-142.27` Cal

D

`-148.5` Cal

Text Solution

Verified by Experts

The correct Answer is:
D
As the process is isobaric `w= -P (V_(2) - V_(1)) = -nR. Delta T`
`= -1 xx 1.98 xx (75) = - 148.5` cal
