A 30.14g stainless steel ball bearing at 117.82 degrees C is places in a constant pressure calorimeter containining 120 mL of water at 18.44 degrees C. If the specific heat of the ball bearing is .474 J/g times degress C, calculate the final temperature of the water. Assume the calorimeter to have neglible heat capacity.
an ice cube contains 925 grams of water. If the initial temperature is at 15 degrees celcius, how many kilojoules of heat are needed to cool and freeze the water at 0 degrees celcius.
