### Drawing a heating curve

How do you know how steep to make the slopes in a heating curve and how long/short to make the lines??

I'm not sure if it matters as long as you show the progression of the reaction correct?

It would depend on the substance you were heating, and you would have to look up the amount of heat needed for each phase change (for the horizontal lines) and the temperature at which each phase change occurs (to determine the steepness of the lines).

The heating curve of water has heat absorbed on the horizontal axis and temperature on the vertical axis. There is a steep slope from solid to melting; the horizontal line for melting is the shortest because it takes the least energy to change from solid to liquid phase. The slope from 0 to 100 degrees is taller and less steep; this represents the temperature increase of liquid water. There is a very long horizontal line to represent the phase change, boiling, because it takes a lot of energy to change from liquid to gas. Then there is another slope in the gaseous phase, representing an increase in temperature.

I believe the "steepness" can also depend on the intervals of your x and y axis.

I do not think you have to go so detailed on the heating curve. As long as your temperatures match up with when it freezes and heats. I provided a link with a heating curve which I think is a pretty good example. Hope it helps!

I dont think it matters in terms of units, however it could matter in relativity to other transitions
