Problem 1: A closed tank, 1 m3 in volume is filled with water at 1 bar 80 °C. A second identical tank contains 20 kg of steam at 20 bar.
a) What is the mass of water in tank 1? b) What is the temperature and phase in tank 2? c) The contents of the two tanks are mixed together in a third closed tank whose volume is 2 m3. Heat is added or removed, as needed, to bring the final temperature to 175 °C. What is the final pressure?
A beaker filled with an equimolar liquid mixture of ethyl alcohol and ethyl acetate evaporates at O°C into still air at 101 kPa (1 atm) total pressure. Assuming Raoult's law applies, what will be the composition of the liquid remaining when half t..
