Three 100. g ice cubes are dropped in 750. grams of water (at 70.00 C) in a Styrofoam cup.

If the ice cubes were initially at -150C, how much energy is necessary to warm and melt the ice cubes?

Will the ice cubes melt?                                  Cice = 0.53 cal/g*OC                Lf = 79.5 cal/g

What is the final temperature of the system?

A 40-g block of ice is cooled to −72°C and is then added to 590 g of water in an 80-g copper calorimeter at a temperature of 26°C. Determine the final temperature of the system consisting of the ice, water, and calorimeter. (If not all the ice melts, determine how much ice is left.) Remember that the ice must first warm to 0°C, melt, and then continue warming as water. (The specific heat of ice is 0.500 cal/g · °C...
