Questions
Three moles of hydrogen at is allowed to expand at constant pressure to twice its original volume. Then amount of heat supplied to the gas is R = 8.3 J/K-mol
detailed solution
Correct option is B
At constant pressure, V2T2=V1T1⇒T2=T1(V2V1)∴ T2=(273+30)×2V1V1=606 K∴ Q=nCP ΔT=3×7×8.32×(606−303)J=26.4 KJTalk to our academic expert!
