Unformatted text preview: 124CYes.128It is to be proven for an ideal gas that the P= constant lines on a Tvdiagram are straight lines and that the high pressure lines are steeper than the lowpressure lines.Analysis(a) For an ideal gas Pv= RTor T= Pv/R. Taking the partial derivative of Twith respect to v holding Pconstant yieldsRPTP=vwhich remains constant at P= constant. Thus the derivative (T/v)P, which represents the slope of the P= const. lines on a Tvdiagram, remains constant. That is, the P= const. lines are straight lines on a Tvdiagram.(b) The slope of the P= const. lines on a Tvdiagram is equal to P/R, which is proportional to P. Therefore, the high pressure lines are steeper than low pressure lines on the Tv diagram.1210Nitrogen gas at a specified state is considered. The cpand cvof the nitrogen are to be determined using Table A18, and to be compared to the values listed in Table A2b....
