Thermal Properties of Matter - Calorimetry Question with Solution | TestHub

A calorimeter of specific heat $0.42\mathrm{J}/{\mathrm{g}}^{\circ }\mathrm{C}$ weighing 40gm contains 50gm of water mixed with 50gm of ice at 0°C and system is in thermal equilibrium. Now steam at 100°C is passed into the mixture until the temperature rises to $20^{\circ }\mathrm{C}$. Take ${\mathrm{L}}_{\mathrm{F}}=80\mathrm{cal}/\mathrm{gm},{\mathrm{L}}_{\mathrm{V}}=540\mathrm{cal}/\mathrm{gm}$. Select the CORRECT alternatives.
