0.2kg of air (modeled as an ideal gas) undergoes an isobaric process in a piston-cylinder aembly, during which the system volume increases twice: V½ = 2v,. 1. Determine the initial temperature of air if its final temperature is 80OK 2. Determine the air pressure in the process if the initial volume occupied by air is 0.1 m². 3. Can this process be adiabatic?
