G3.6 - Isaac Physics Heat Capacity
I have no resources on this type of question or have seen anything about mixtures of different materials for specific heat capacity, does anyone have any advice for getting to an answer with this question?
First Substance:
Water, 3.2kg, 83∘C, 4180Jkg-1C-1
Second Substance:
Paraffin, 4.3kg, 18∘C, 2030Jkg-1C-1
What is the final temperature in ∘C?

Write separate equations for temperature change of water and paraffin, assuming final temperature of both is the same, and that heat transfer from water = heat transfer to paraffin. Solve as simultaneous equations.

Yes, for this I did two equations. I don't think I'm doing this right and I'm unsure how to set it up. The answers I am getting are not being accepted.

Can you post your working here?

Oh, don't worry anymore I found it out. Thank you so much for trying to help earlier. I ended up doing this which didn't need simultaneous equations.
let:
m1 = mass of hotter substance
m2 = mass of colder substance
c1 = spec heat cap hotter substance
c2 = spec heat cap colder substance
Th = Temp of hot
Tc = Temp of cold
t = temp change
energy lost = energy gained
m1c1(Th - t) = m2c2(t - Tc)
solve for t

It would be better if you could show us how you get 224.
As this is an old thread, we would close this old thread soon.
If you cannot post a reply before it is closed, you can always start a new thread and link to this thread.
