![The volume of 1.5 kg of hydorgen in a piston-cylinder device is initially 6 m. Now hydrogen is compressed to 2.5 m' while its pressure is maintained
constant at 190 kPa.Considering hydrogen as an ideal gas, determine
1) the initial temperature (T), final temperature (T2) of hydrogen and the work required (Wh in) to compress the gas, in kJ.
(See Table A-1 for value of R of hydrogen)
T1= 230.36 K, T2 = 92.14 K, Wp in = 570 kJ
Oa.
T1= 184.29 K. T2 = 76.79 K, Wb in = 665 kJ.
T1= 161 25 K. T2 = 69 11 K. Wb in = 760 kJ
Tq = 147 43 K. T2 = 64.5 K. Wh in = 855 kJ
