Liquid chlorobenzene goes through a process where there is negligible heat flow and no work done on the surroundings. initially it is at 330 k and 3,500 kpa. at the end of the process the final pressure is 2,000kpa. estimate the temperature change and the entropy change of chlorobenzene.

Water is siphoned from a large tank and discharges into the atmosphere through a 50-mm diameter tube. the end of the tube is b = 2.6 m below the tank bottom which is a = 6.7 m deep, and viscous effects are negligible. determine the maximum height h over which the water can be siphoned without cavitation occurring. atmospheric pressure is 101.4 kpa, and the water vapor pressure is 1.79 kpa (absolute). report your answer in meters to two decimal places.
