What should be the temperature of 1g of ice, so that when it’s added to 9g of water, lowers the temperature of water by 10°C? Sw = 1cal/ g°C, Sice = 0.5cal/ g°C, Lfus= 80cal/g.

Calorimetry is the science or act of measuring changes in state variables of a body for the purpose of deriving the heat transfer associated with changes of its state due, for example, to chemical reactions, physical changes, etc.
