A40 g block of ice is cooled to -69°c and is then added to 590 g of water in an 80 g copper calorimeter at a temperature of 22°c. determine the final temperature of the system consisting of the ice, water, and calorimeter. 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 = 2090 j/kg°c.

Explanation:

Heat released by water and copper calorimeter if they reach to Zero degree celcius from initial temperature

Q = 63082.8 + 677.6 = 63760.4 J

now heat required to raise the temperature of ice to 0 degree Celcius

now heat required to melt the ice

total heat required to melt the ice will be

now remaining heat after whole system is at zero degree celcius is

now the final temperature of the system is given as
