Note: 1 atm= 101,325 Pa or 1.0 x 105 Pa
a. It expands at constant pressure to twice its initial volume?
b. It is compressed at constant pressure to ¼ of its initial volume?
4. A gas is compressed at a constant pressure of 0.7 atm from 8 liters to 1.5 liter and releases 600 J of thermal energy. What is the work done by the gas?
2. All liquids have characteristic vapor pressure that vary with temperature. The characteristic vapor pressure for pure water at 22°C is 19.827 mm Hg and at 30.0°C is 31.824 mm Hg. Use these data to calculate the change in enthalphy per mole for the vaporization
The salt cesium sulfate is soluble in water. When 22.7 g of Cs2SO4 is dissolved in 120.00 g of water, the temperature of the solution decreases from 25.00 to 22.96 °C. Based on this observation, calculate the enthalpy of dissolution of Cs2SO4 (in kJ/mol). Assume that the specific heat of the solution is 4.184 J/g °C and that the heat absorbed by the calorimeter is negligible.
