Expert Solution
Step 1

Soln

A)

First ice will melt at 0 C from solid state to liquid state then liquid water rise in the temperature from 0 C to 25.0 C

so we need to use the enthaly of fusion of ice and the sepcific heat of the ice

enthalpy of fusion of ice = 334 J /g

and specific heat of liquid water = 4.184 J per g C

now lets calculate the amount of heat needed to this process

total heat is the sum of the delta H fusion and amount of heat needed to rise the temperature of the water
