Question details

Question:

An insulated piston-cylinder device contains steam at 295 kPa , 210 ∘C, occupying a volume of 1 m3, and having a specific volume of 0.719 m3/kg . It is heated by an internal electrical heater until the volume of steam doubles due to an increase in temperature.

Part A Determine the final specific volume of steam Express your answer to four significant figures 3 m /kg Submit Request Answer Part B If the diameter of the piston is 20 cm and the outside pressure is 100 kPa, determine the mass of the weight placed on the piston to maintain a 295 kPainternal pressure Express your answer to four significant figures m- kg Submit Request Answer Part C Calculate the WB(magnitude only) done by the steam Express your answer to three significant figures. kJ Submit Request Answer Part D Calculate the amount of WM(magnitude only) transferred into the weight
