I'm somewhat stumped on this question from my son who's in Grade 10 Physics.
Question:
You put 100g of ice into a glass of 2400g of water at 10C.
What is the final temperature of the water?
Hmmm. Sounds simple,
BUT,
I know,
Q= m(delta)H(fus)
where (delta)H(fus)= 333J/g for water
and
Q=mc(delta)T
where m=mass(g),
c=specific heat of water = 4.18J/gC
BUT we need to find the (delta)T from Tintial to Tfinal.
Where do I start? Or am I missing something here?
