1. Determine the volume occupied by a 1 mole of an ideal gas at 27° C and 1 atm pressure. Ammonia gas at 27° C and 1 atm is passed at a rate of 41 cm3 s-1 into an apparatus where it flows over an electrically heated wire of resistance 100 . When the heating current is 50 mA the gas leaves the apparatus at 31.09° C. Calculate Cp and CV for ammonia assuming it behaves as an ideal gas. 3. I know it a pretty simple problem but it has been a while since i practiced any thermal physics. I have determined the initial volume occupied by the ideal gas using: pV=nRT... and got 0.025m^2 However i am clueless as to how to approach the rest of the problem. any help would be greatly appreciated.
