what will the maximum temperature reached by the resulting solution? [Assume that there is no heat loss to the container, that the specific heat of the final solution is 4.18 J/g*C, and the density of the final solution is that of water.]
Consider n moles of ideal gas kept in a heat isolated cylinder (all processes are adiabatic) with a piston at extrnal pressure P(i), and at the temperature T(i). the extrnal pressure is suddenly changed to P=2P(i), and we wait for the system to eq..
