A) \[2250\,cal\]
B) \[2250\,J\]
C) \[4500\,J\]
D) \[6428\,cal\]
Correct Answer: D
Solution :
Here \[n=\frac{M'}{M}=\frac{0.04\times {{10}^{3}}}{28}\] mole Nitrogen is a diatomic gas \[{{C}_{V}}=\frac{5}{2}R\] As to double the rms speed of molecules the temperature of gas should be raised to 4 times. \[\Delta T=1200-300=900k\] As the gas is enclosed in the vessel V = constant \[\therefore {{(\Delta Q)}_{v}}=n{{C}_{v}}\Delta T\]You need to login to perform this action.
