Water, initially saturated vapor at 11.5 bar, fills a closed, rigid container. The water is heated until its temperature is 200°C. For the water, determine the pressure at the final state, in bar.
Water, initially saturated vapor at 14.1 bar, fills a closed, rigid container. The water is heated until its temperature is 200°C. For the water, determine the pressure at the final state, in bar.
A rigid container with a volume of 10 cubic meters contains are at 5 degrees C with a relative humidity of 100%, a pressure of 1 bar, and 0.25kg of liquid water at 5 degrees C. If the container is heated until the mixture reaches a temperature of 80 degrees C, determine the final pressure and relative humidity of mixture. Also, determine the percent of the volume of the container occupied by the liquid at the initial condition, and discuss...
Water, initially saturated vapor at 2 bar, fills a closed, rigid container. The water is heated until its temperature is 400°C. For the water, determine the heat transfer, in kJ per kg of water.

Two moles of carbon dioxide gas at 35°C are heated to 250°C in a container while the volume is kept constant. The density of the gas in the container will O increase. O decrease. O remain the same O reach a value of zero. There is not enough information given to correctly answer this question.
2.00 mol of helium is heated in a rigid container (constant volume). If 80.0 J are added to the container, what is the change in temperature of the gas?
5 kg of water at 2 ° C, 2 kg of ice at 0 ° C and 5.5 kg of water vapor at 120 ° C and 1.5 bar are mixed in a fixed-volume container. What is the final temperature of the mixture? How much water vapor condenses? Suppose that the volume of the container is constant with a value equal to the initial volume of the water vapor and that the container is insulated. Suppose it is a discontinuous...
