A) 62 J
B) 104 J
C) 124 J
D) 208 J
Correct Answer: D
Solution :
[d] The heat is supplied at constant pressure. Therefore, \[Q=n{{C}_{p}}\Delta t\] \[=2\left[ \frac{5}{2}R \right]\times \Delta t=2\times \frac{5}{2}\times 8.31\times 5=208J\] \[\left( \therefore {{C}_{p}}=\frac{5}{2}R\text{ for mono-atomic gas} \right)\]
