Required information A 0.9- L glass of water at 20C is to be cooled with ice to 5C. The density of water is 1kg/L, and the specific heat of water at room temperature is c=4.18kJ/kgC. The specific heat of ice at about 0C is c=2.11 kJ/kgC. The melting temperature and the heat of fusion of ice at 1atm are 0C and 333.7kJ/kg. Determine how much ice needs to be added to the water, in grams, if the ice is at 20C. Also determine how much water would be needed if the cooling is to be done with cold water at 0C. The amount of ice that needs to be added is g. The amount of water required is g
