One mole of an ideal gas, initially at 30 [°C] and 1 [bar], is changed to 130 [°C] and 10 [bar] by two different mechanically reversible processes: • The gas is first heated at constant volume until its temperature is 130 [°C], then it is compressed isothermallyuntil its pressure is 10 [bar].• The gas is first compressed adiabatically; then it is heated isobarically to 130 [°C] and 10 [bar]. Calculate Q, W, ΔU, and ΔH in [J] for each case. Take Cp = 5/2R and Cv = 3/2R.
