I'm somewhat stumped on this question from my son who's in Grade 10 Physics.(adsbygoogle = window.adsbygoogle || []).push({});

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?
