A piston-cylinder assembly contains air at 210 kPa and occupies a volume of 0.01m. Thepiston is attached to one end of a spring and the other end of the spring is fixed to a wall. Theforce exerted by the spring on the piston is proportional to the decrease in the length of thespring. The ambient atmospheric pressure is 100 kPa. Now, the air in the cylinder is heated tillthe volume is doubled and at this instant it is found that the pressure of the air in the cylinderis 600 kPa. Sketch the process on p-v diagram and calculate work done by the gas.
2.5 kW of solar energy comes upon renovation of a house. 25% of this incoming energy is lost to the environment, and the remaining energy is used to increase the temperature of the water passing through the solar panel from 30 oC to 60 oC.
