Would you be better off buying it on a warm day? Explain.The piston cylinder set shown in Figure 01 contains 1 liter of water at 105 ºC with a titer equal to 0.85 (% steam = 85.00%). When the assembly is heated, the piston moves and when it meets the spring the volume is equal to 1.5 liters. Heating continues until the temperature reaches 600 ºC. Knowing that the piston diameter is 150 mm and that the spring constant is 100 N / mm. Calculate: a) The pressure in the water at the end of the process.b) The total work done.c) The amount of heat transferred to heat the system from 105 ºC to 600 ºC.In a hypothetical diesel engine the fuel is compressed from 528mL to 39.7 mL.
