What is the pressure of the gas inside the container?1 kg of benzene is poured into a flask and heated to 353 K (the boiling point of benzeneat 1 atm.) using a heating element that has a power of 700 W (we ignore thatit's probably not so healthy and smart to do). After 5 minutes, when the benzene has stoodboiling point, the heating element is taken up, and the remaining mass of benzene in the flaskmeasured at 470 grams. Determine the enthalpy of vaporization of benzene.

Achamber contains 2 kg of water at 800 kPa pressure and 80 oC temperature. The other compartment isis empty (vacuum). Then the steel curtain is removed and the water fills the whole container. EndIn the equilibrium state, since the pressure of the water is 10 kPa, the final temperature of the water andCalculate the volume of the tank.Show complete solutions and enclose all final answers in a box. Round off final answers to 4 decimal places and use floating values for intermediate answers. A gas column is separated into two segments by a non-permeable partition. On the first segment is 1.63 moles of Helium with volume V1 and on the second segment is 3.84 moles of Oxygen gas with volume V2. Consider both gases to be ideal and at the same pressure P and temperature T. If the partition is removed, calculate the change in entropy of the gaseous system.
