A gas has pressure ( 1 bar ) , temperature ( 15 ° C) and density ( 1,855 kg / m3 ). Calculate the value of R when heating (0.9 kg) of this gas from a temperature of (15 ° C) to (250 ° C) at a constant pressure, and the required temperature is (175 kJ). Calculate Cp and Cv and calculate the change in internal energy and work A transferred A gas has pressure ( 1 bar ) , temperature ( 15 ° C) and density ( 1,855 kg / m3 ).
