Homework Statement
Question (b) (iii)
Homework Equations
The Attempt at a Solution
The energy required to melt the ice is
Q1=mL=3*0.025*3.3*10^5=24750J
The energy released by water is
Q2=mcT=0.33*4200*(22-T)
Shall I calculate the energy that the ice needs after it melts into water?
i.e. Q3=0.075*4200*(0-T)
So Q1+Q3=Q2 and then just solve for T?
Is that right? I did it this way but got a different answer to the mark scheme.
