Problem 1: A sealed rigid tank is filled with 1 kg of steam at 200 °C and 10 bar.
a) What is the volume of the tank?
b) 0.5 kg of steam are removed from the tank. If the temperature remains at 200 °C, what is the new pressure in the tank?
c) What is the state of the steam at the end of part b (e.g., liquid, vapor, saturated, superheated)?
d) How much heat must be added to bring the pressure back to 10 bar?
e) What is the temperature at the end of step (d)?
