Physics - Heat & Thermo Question with Solution | TestHub

In a container of negligible heat capacity, $200\mathrm{gm}$ ice at $0^{\circ }\mathrm{C}$ and $100\mathrm{gm}$ steam at $100^{\circ }\mathrm{C}$ are added to $200\mathrm{gm}$ of water that has temperature $55^{\circ }\mathrm{C}$. Assume no heat is lost to the surroundings and the pressure in the container is constant $1.0\mathrm{atm}$. ($L_f=80$ cal/gm, $L_v=540$ cal/gm, $s_w=1$ cal/gm${}^{\circ }\mathrm{C}$)
