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. Take the density of liquid C8H18 to be 0.703 g cm-3 and its specific heat to be 2.22...

10 moles of an ideal gas expands irreversibly against an unknown constant external pres- sure, Pert, from an initial volume Vİ-1 L to a final volume ½ 11 L. In the process, the temperature of the gas falls from T350 K to T2 250 K, and it absorbs heat q+7 L atm from the surroundings. (a) What is the external pressure, Pert (in atm)? [Note: this is an ideal gas, so its internal energy depends only on its temperature.] (b)...
