Agas mixture contains 30.0 mole% h2o(v) and 70.0 mole% n2. the gas temperature and absolute pressure at the start of each of the three parts of this problem are 75°c and 900.0 mm hg. ideal gas behavior may be assumed in every part of this problem. a. if some of the gas mixture is put in a cylinder and slowly cooled at constant pressure, at what temperature would the first drop of liquid form? °c b. if a 30.0 liter flask is filled with some of the gas mixture and sealed, and 70.0% of the water vapor in the flask is condensed, what volume would be occupied by the liquid water? cm3 what would be the system temperature? °c c. if the gas mixture is stored in a rigid-walled cylinder and a low-pressure weather front moves in and the barometric (atmosopheric) pressure drops from 760 mm hg to 720.0 mm of hg, what would be the new gauge pressure in the cylinder? mm hg

Apump is used to circulate hot water in a home heating system. water enters the well-insulated pump operating at steady state at a rate of 0.42 gal/min. the inlet pressure and temperature are 14.7 lbf/in.2, and 180°f, respectively; at the exit the pressure is 60 lbf/in.2 the pump requires 1/15 hp of power input. water can be modeled as an incompressible substance with constant density of 60.58 lb/ft3 and constant specific heat of 1 btu/lb or. neglecting kinetic and potential energy effects, determine the temperature change, in °r, as the water flows through the pump.
