Explain the gas inside a cylinder expands against a constant external pressure of 2.8 bar from a volume of 0.53 L to a volume of 0.89 L. In doing as a result it turns a paddle immersed in 1.24 L of water. Compute the temperature rise of the water assuming no heat loss to the surroundings or frictional losses in the mechanism. Obtain the density of water to be 1.00 g/cm3 and its specific heat to be 4.184 J/g/K.
