can i know the N of 11 pounds of nitrogen?because i can't get it...

then that equation will be like this V2/V1=e^15/c ?? right? how can i convert 11 punds of nitrogen gas into molecules? i can't undserstand it..sorry for that,..thanks again

i get this equation 15/C=in(V2/V1), how can i get C constang in PV=NkT?this is what i did.. (58psia)V=N(1.38066X10-23 J/K)(90F) how can i get N?and V? and if i get V, what is it V1 or V2? thanks for answering my question..

how about the final pressure?its also the same 58 psia?

if that's the case.why is it internal energy should be in BTU/lb??

how could i find the internal energy if it has only 1 temperature given??how could i know Cv??thanks

a piston cylinder device contain 11 pounds of nitrogen gas at 58 psia and 90 degree farenheit. during the process the gas follows PV=C expansion which 15 BTU of work is done by the system, determine: a) charge of internal energy (BTU/lb) b)charge in entholpy (KJ) c) heat transferred in BTU...

can somebody help me in solving this problem..thanks.. A gaseous substance whose properties are unknown, except as specified below, undergoes an internally reversible process during which V = (-0.1p + 300)ft cube, when p is in psfa. (a) for this process, find -/ V dp and...
