Five moles of Hydrogen gas initially at STP is compressed adiabatically so that its temperature becomes \(673 \mathrm{~K}\). The increase in internal energy of the gas is \(\left(R=8.3 \mathrm{~J} \mathrm{~mol}^{-1} \mathrm{~K}^{-1}, \gamma=1.4\right.\) for diatomic gas \()\)
- A 80.5 kJ
- B 21.55 kJ
- C 41.50 kJ
- D 65.55 kJ
Answer & Solution
Correct Answer
(C) 41.50 kJ
Step-by-step Solution
Detailed explanation
Given, temperature, \(T_2=673 \mathrm{~K}\) initial temperature \(T_1=273 \mathrm{~K}\) rate of heat flow, \(R=8.3 \mathrm{~J} \mathrm{~mol}^{-1} \mathrm{~K}^{-1}\) \(\gamma=1.4\) for diatomic gas, moles of hydrogen gas, \(n=5\) Now, change in internal energy due to adiabatic…
