3-0.1 kg of steam is enclosed inside a piston-cylinder steam. Piston is attached to a fixed support by a linear spring as shown in image. Initially steam has a pressure of

P₁= 200 kPa and specific volume of v=0.96 m²/kg. Heat is added to the steam until its specific volume increases to v₂ = 1.34 m²/kg and pressure to P₂ = 300 kPa. a) Find the initial and final volume of the steam (2 Pts) b) Work of the system on the environment during this expansion (4 Pts) c) Heat added to the system for this expansion (4 Pts) Note: You may use tables for only 2 decimal places of specific volume. e www
