The piston has no mass and no friction. There is 2 kg of water and the initial Temp is 99.61 C and initial volume is 1m3 . Heat is added until there is contact with a spring 0.694m away. The sping is compressed a total of 0.3190m and the pressure reaches 200kPa. Once it stops at this more heat is added until it is 300kPa. Ambient temp is 300k. Find the heat transferred and work done from initial state until the piston touches the spring.
