An ideal gas is enclosed in a piston, and 1600 j of work is done on the gas. as this happens, the internal energy of the gas increases by only 500 j. during this process, how much heat flows into or out of the ideal gas? enter a positive number to indicate a heat flow into the gas or a negative number to indicate a heat flow out of the gas.

An object in mechanical equilibrium is an object

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.
