Part A How much ice at a temperature of-24.7 Cmust be dropped into the water so that the final temperature of the system will be 35.0°C Take the specific heat of liquid water to be 4190J/kg.K,the specific heat of ice to be 2100 U/kg .K,and the heat of fusion for water to be 3.34x105 J/kg mice Submit Hints My Answers Give Up Review Part incorrect: Try Again; 5 attempts remaining Continue Provide Feedback

Explanation / Answer

First find the heat removed from the water

Q = mc(delta T)

Q = (.25)(4190)(66.6 - 35)

Q = 33101 J

That amount of heat needs to be taken from the ice.

We need the ice in 3 phases...

Q = mc(delta T) + mH + mc(delta T)

33101 = m(2100)(24.7) + m(3.34 X 105) + m(4190)(35)

33101 = 532520m

m = .0622 kg
