7- A piston cylinder device contains 5 kg of water at 150 kPa and 25°C. The cross-sectional area of the piston is 0.1 m². Heat is transferred to the water causing part of it to evaporate and expand. When the volume reaches 0.2 m', the piston reaches a linear spring whose spring constant is 100 (kN/m). More heat is added to the water until the piston rises 20 cm more. Determine: (1) the final pressure and temperature, (2) the work done during this process by spring and by system against spring, (3) the amount of heat transferred to water, and (4) show this process on P-V diagram

A Block has the potential to produce up to 3000 MWh of geothermal energy when the project is developed to completion. In the region, the average geothermal temperature gradient is 20 °C/km, the maximum depth that can be reached using conventional drilling technology is 10 km, the average annual surface temperature is 25 °C and the rock under the surface in that region has a density of 2600 kg/m3 and a specific heat of 1000 J/kg.K. Determine the minimum mass of rock required to meet this demand.
