The gas inside a cylinder expands against a constant external pressure of 0.953 atm from a volume of 4.51 L to a volume of 14.50 L. In doing so, it turns a paddle immersed in 0.962 L of liquid toluene (C7H8). Calculate the temperature rise of the liquid, assuming no loss of heat to the surroundings or frictional losses in the mechanism. Take the density of liquid C7H8 to be 0.867 g cm-3 and its specific heat to be 1.69...
The gas inside a cylinder expands against a constant external pressure of 0.906 atm from a volume of 3.61 L to a volume of 14.50 L. In doing so, it turns a paddle immersed in 0.926 L of liquid octane (C8H18). Calculate the temperature rise of the liquid, assuming no loss of heat to the surroundings or frictional losses in the mechanism.

He gas is confined to a piston and cylinder with a mechanical stop that prevents the cylinder from expanding. The temperature of the gas is 298 K, the volume of gas in the cylinder is 1.20 L and its pressure is 2.15 bar. The ideal gas EOS is very accurate for He under these conditions. Starting from the final state of the He gas in part (b), the gas (and apparatus) was cooled from 298 K to 263 K. The...
