The cooling curve of naphthalene. Image credit MediaWiki
- When steam is cooled into condenses into a liquid
- If the liquid is cooled further it solidifies
- A cooling curve can be thus obtained
- This is a reverse of the heating curve
- As a vapour changes into a liquid it gives out heat which prevents a drop in temperature
- When the liquid solidifies the temperature remains the same while heat is given out
