Specifc heat, latent heat -- Comprehensive Problem Solving An foam cup with negligible mass contains liquid sweet water with a mass of 0.250 kg and a temperature of 64.0 C . Take the specific heat of liquid water (and sweet water) to be 4190 J/kgK , the specific heat of ice to be 2100 J/kgK , and the latent heat of fusion for water to be 3.34105 J/kg . How much ice at a temperature of -11.0 C must be dropped into the sweet water so that the final temperature of the system will be 34.0 C ? How much ice at a temperature of -11.0 C must be dropped into the sweet water so that the final temperature of the system will be 34.0 C ? Keep 3 digits after the decimal point, in kg
