A flow rate of 1000 kg/h of water at 21.1 C is heated to 110 C when the total pressure is 244.2 kPa in the first stage of a process. In the second stage at the same pressure the water is heated further, until it is all vaporized at its boiling pt. Calculate total enthalpy change in the first stage and in both stages.
A solution is prepared by dissolving 270 g of sucrose (C12H22O11) in 624 g of water. What is the vapor pressure of this solution at 30°C? (The vapor pressure of water is 31.8 mmHg at 30°C.)
A weather balloon at Earth's surface has a volume of 3.9 L at 275 K and 775 mm Hg. if the balloon is released volume reaches 4.2 L at 711 mm Hg what is the temperature.
A gas expands and does pv work on its surroundings equal to 347 J. At the same time, it absorbs 127J of heat from the surroundings, what is the change in energy of the gas.
We add excess Na2CrO4 solution to 16.0 mL of a solution of silver nitrate (AgNO3) to form insoluble solid Ag2CrO4. When it has been dried and weighed, the mass of Ag2CrO4 is found to be 0.380 grams.
