A) 50 R
B) 60 R
C) 70 R
D) 80 R
Correct Answer: C
Solution :
Heat supplied at constant pressure \[Q=\mu {{C}_{p}}\Delta T\] Here, \[\Delta T={{40}^{o}}C\] \[{{C}_{p}}=\frac{7}{2}R\](for diatomic gases) Number of moles,\[\mu =\frac{14}{28}=\frac{1}{2}\] \[\Rightarrow \]\[Q=\frac{1}{2}\times \frac{7}{2}R\times 40=70R\]You need to login to perform this action.
