Question

A 20.0 g ice cube is dropped into 300 g of water in a thermally insulated
container. If the water is initially at 20.0°C, and the ice comes directly from a
freezer at -18.0°C, what is the final temperature in °C at thermal eqilibrium?
Heat of transformation for ice is Lp=79.5 cal/g. Specific heat for water is 1.00
cal/gK, and for ice 0.530 cal/gK.
