Because of tectonics plates and the top aka surface of the earth is where the pressure is released and the reactions occur for example the roads splitting... this is just how i would answer it.
Q in = Q out
0.25 x 4200 x (90-t)=0.05 x 4200 x (t-0)
1050 (90-t)=210t
94500-1050t=210t
94500=1260t
t=75°
Answer:
The correct answer is - 1.
Explanation:
The one cubic centimeter is equal to the one mililitter of a liquid. It is same de to the fact that volume of water that fits in a one cubic centimeter is equal to the liquid present in one mililiter of a liquid.

A quick, easy way to decide whether there was a chemical change
is to look and see whether there are NEW substances after the
event, that weren't there when it started.
This particular scenario started out with fat and sodium hydroxide (lye).
And then, suddenly, POOF ! Soap and glycerin showed up. Where did
THOSE come from ? They came from the molecules in fat and lye,
getting broken up and recombined to make different substances.
THAT's exactly a chemical change.
