A 2.0 Liter container is filled with 250 grams of water and 1.0 gram of nitrogen gas (N2). The container is heated to 75°C and allowed to equilibrate. The liquid water occupies the bottom of the container, and the void above the liquid contains the nitrogen gas and some water vapor. Assume that the nitrogen which dissolves in the water is negligible and that the density of water is a constant 1000 kg/m3. (a) Find the volume occupied by the water.
(b) Find the partial pressure of the nitrogen gas.
(c) Find the partial pressure of the water vapor. The Antoine equation coefficients are given below. The units on the coefficients are mmHG and °C.
A. 7.96681
B. 1668.210
C. 228.000
(d) What is the total pressure in the vapor phase of the container?

A3-mm-thick panel of aluminum alloy (k 177 w/m-k, c 875 j/kg-k and ? = 2770 kg/m) is finished on both sides with an epoxy coating that must be cured at or above t,-150°c for at least 5 min. the production line for the curing operation involves two steps: (1) heating in a large oven with air at ts,0-175°c and a convection coefficient of h, 40 w/m2. k, and (2) cooling in a large chamber with air at 25°c and a con- vection coefficient of he 10 w/m2.k. the heating portion of the process is conducted over a time interval te which exceeds the ime required to reach 150°c by 5 min (h = r + 300 s). the coating has an emissivity of ? = 0.8, and the temperatures of the oven and chamber walls are 175 and 25°c, respectively. if the panel is placed in the oven at an initial temperature of 25°c and removed from the chamber at a safe-to-touch tempera ture of 37°c, what is the total elapsed time for the two-step curing operation?
