4-19 The equation of state of a gas is given as (P = 10/ 2) = RuT, where the units of and P are m3/kmol and kPa, respectively. Now 0.5 kmol of this gas is expanded in a quasi-equilibrium manner from 2 to 4 m3 at a constant temperature of 300 K. Determine a) the unit of the quantity 10 in the equation and b) the work done during this isothermal expansion process. | |
