A monoatomic gas does $100 J$ of work when it is expanded isobarically. How much of heat is given to the gas in the process

A
$150 J$
B
$200 J$
Correct answer
C
$250 J$
D
$300 J$

Solution

Work done in an isobaric process is given by
$W = n R ∆ T \Rightarrow n R ∆ T = 100 J$ .
For isobaric process heat is calculated by
$Q = n C_{P} ∆ T \Rightarrow Q = n \frac{5}{2} R ∆ T \Rightarrow Q = 250 J$

Hence, the correct answer is option: 'C'.
