At 10 bar, 100 kg of saturated steam, 20 kg of ice (0oC), and 80 kg of water (20oC) are sealed together in a perfectly insulated thermos. The pressure is kept constant at 10 bar. Determine the final state of the mixture at thermal equilibrium. Assume for ice that the energy of melting is equal to the enthalpy of melting (Table B.20) and is independent of pressure. Use the approximate constant pressure heat capacity (the constant Cp approx., NOT the polynormial expression) found in Table B.17. Use Table B.16 (steam tables) when possible.  Draw a detailed diagram of the system. Referring to your diagram, check all the following statements that apply: Group of answer choices The system is at constant pressure. The process is adiabatic. There is material flowing into the system. The initial temperature of the saturated steam can be found in the steam tables. The only work is done by the system. The system is at constant volume. There is no work. This is a closed system.

2) Two glass bulbs, one on the left with a volume of 2 liters and the other on the right with avolume of 6 liters, are connected to one another by a thin tube that is initially closed by astopcock. The bulb on the left has 0.1 moles of ideal gas, and the bulb on the right isevacuated. The system is in thermal equilibrium with the surroundings at 300K. When thestopcock is opened, the gas flows out to fill both bulbs. Calculate A for this process. If wewere to insert a propeller to extract work as the gas flows from left to right, what is themaximum amount of work that we could possibly extract?
