Let the final temperature vary from 2500 to 3500 K. For each of the two cases, plot the rate of heat supplied as a function final temperature. 820 | Thermodynamics 1672 Consider a rubber plate that is in contact with nitrogen gas at 298 K and 250 kPa. Determine the molar and mass density of nitrogen in the rubber at the interface. 1673 A wall made of natural rubber separates O2 and N2 gases at 25C and 500 kPa. Determine the molar concentrations of O2 and N2 in the wall. 1674 Consider a glass of water in a room at 27C and 97 kPa. If the relative humidity in the room is 100 percent and the water and the air are in thermal and phase equilibrium, determine (a) the mole fraction of the water vapor in the air and (b) the mole fraction of air in the water. 1675E Water is sprayed into air at 80F and 14.3 psia, and the falling water droplets are collected in a container on the floor. Determine the mass and mole fr...
