2 kg of air contained in a piston-cylinder assembly undergoes a process from the initial
state of T₁ = 400K, v₁ = 0.5 m³ to the final state of T₂ = 600K, v₂ = 0.8 m³. Assume the ideal gas model
with cv = 0.72 kJ/kg . K for the air. Kinetic and potential energy effects are negligible.
Can this process occur adiabatically? Demonstrate it with formulas and calculations.

Determine the change of specific entropy in the isobaric process from the same initial state, T₁ =
400K, v₁ = 0.5 m³, to the same final specific volume: v₂ = 0.8 m³.
Determine the change of specific entropy in the isochoric process from the same initial state, T₁ =
400K, v₁ = 0.5 m³, to the same final temperature: T₂ = 600K.
Determine the change of specific entropy in the isothermal process from the same initial state, T₁ =
400K, v₁ = 0.5 m³, to the same final specific volume: v₂ = 0.8 m³.
