A spring-loaded piston-cylinder device contains m = 1kg of carbon dioxide. Initially, the spring has no force on the piston and P₁=:
= 500kPa,
T₁=150K, V₁ = 0.1m³. Heat is transferred to the gas, causing the piston to rise and to compress the spring. At the state 2, T₂=900K,
V₂=0.3m ³. The gas is an ideal gas.
