Question details

I1. The pressure of a gas is given by Pwhere P is in atmosphere and V is in litres. If the gas expands from 20 to 60 L and undergocs an increase in internal energy of 225 cal. How much hcat will be absorbed during the process? 12. 5 moles of an ideal gas was initially at 315 K and 20 atm. The expansion of gas takes place adiabatically when the external pressure is reduced to 7 atm. What will be the final temperature and volume? Also calculate the work done during the process, given that Cp -8.58 cal/mol/ C.
