can't seem to solve this problem:
3.98 ) Consider a gas mixture whose apparent molecular weight is 33, initially at 3 bar and 300k, and occupying a volume of 0.1m3. The gas undergoes an expansion during which the pressure volume relation is pV1.3=constant. and the energy transfer by heat to the gas is 3.84 kJ . Assume the ideal gas model with cv = 0.6 + (2.5 x 10-4)T, where T is in K and cv has units of kJ/kg. Neglecting kinetic and potential energy effects, determine
(a) the final temp in K (c) the final volume in m3
(b) the final pressure in bar (d) the work in kJ
I was told to use eqation:
Q=m*R(t2-t1)/(1-n)+cv*(t2-t1) use tis to start and get t2. and the rest should fall into place.but the units are all messed up.
