1.) A 11.6-kg block of ice has a temperature of -14.5 Â°C. The pressure is one atmosphere. The block absorbs 6.87 x 106 J of heat. What is the final temperature in degrees Celsius of the liquid water?

2.) A thermos contains 156 cm3 of coffee at 86.4 Â°C. To cool the coffee, you drop two 11.4-g ice cubes into the thermos. The ice cubes are initially at 0 Â°C and melt completely. What is the final temperature of the coffee in degrees Celsius? Treat the coffee as if it were water.

Thanks
