## How to draw a heating curve?

isochoric/isometric: $\Delta V = 0$
isothermal: $\Delta T = 0$
isobaric: $\Delta P = 0$

### How to draw a heating curve?

On the workbook, no.5 on the quiz preparation, it asks us to draw a heating curve based on the enthalpy of fusion, enthalpy of vaporisation, and the heat capacity for solid, liquid and gas phases. How do I do that?

Hint: flat lines for the phase changes and sloped lines for the heating (temperature-changing) parts

Also make sure the length of your horizontal line is proportional to how much heat should be supplied, and that your slopes accurately represent the different heat capacities (smaller heat capacities will have steeper slopes because less energy needs to be absorbed for the temperature to rise).

The horizontal lines are the phase changes and the slopes are based off of the heat capacities. The x axis is the amount of heat inputted and the y axis is the temperature.
