6th edition 6.41

Postby katherinemurk 2B » Wed Feb 06, 2019 5:48 pm

In the solutions manual they add the reaction enthalpy of fusion to the equation q=mCdeltaT when calculating heat of the ice cube. Can someone please explain why this is done?

Assuming no heat is lost, heat from the water will be transferred to the ice cube. Remember that it is an ice cube (solid), at 0 degrees Celsius. The ice will melt and then increase in temperature, which is why you need to add the heat of fusion to the equation for heat.
