"The slope of the line where the temperature of water changes is directly proportional to the specific heat of water."

The graph is a standard phase transition diagram.

I think not. My mind could have tripped though. The question asked you to choose the wrong statement.

If you look at the formula relating c and (delta T), you'll see that they are multiplied together, making them inversely proportional:

Q = m*c*(delta T)

If I rearrange the equation to solve for (delta T), then it makes the relationship even more obvious:

(delta T) = Q/(m*c)

(delta T) 1/c

Temperature is proportional to Q (heat).

So that answer that I chose was the correct one? (The answer being the statement quoted)? Because T/Q = Slope

T/Q = 1/ m*c

....which would mean that the slope is not directly proportional to specific heat, which means that the quoted statement (which I chose) is in fact the correct answer, since the question asked to choose the false statement???

I hope...lol

Yeah, you're right. The statement was false, lol.
