So in this question, we want to know how much heat is associated with heating something that starts as ice at negative 10 degrees celsius all the way up to steam at 110 degrees celsius.
00:13
So before we do this, we kind of have to have a picture of what's going on.
00:16
So we are starting as a solid at negative 10 degrees.
00:20
We have to heat it up to zero, which is going to be, which is going to require some amount of heat that will be determined by q equals mc delta t because of a change in temperature.
00:31
Then we will melt it, which will be calculated by q equals mhf, then we will heat the liquid, which is another mc delta t, then we will boil, which is q equals mhv, and then we're still going to heat the gas, the steam, which is another q equals mc delta t problem.
00:57
And what we can actually do is add all of these heat.
01:02
Values together in order to calculate the final amount of heat exchanged.
01:09
So if we take each of these formulas, we know that it's a constant amount of 10 grams for each time...
