1) Consider 2kg mixture of H2 and N2 ideal gases inside a closed piston-cylinder device at 150kPa and 100o C. This mixture has 0.4 mole fraction of H2. This mixture undergoes a constant pressure heating process to final temperature 180° C (inside the piston-cylinder device) . For this mixture,
i) determine R, M, Cv and initial volume of the mixture.
ii) Heat energy added to the mixture.
iii) Work done during the heating process.
