Latent Heat (VCE SSCE Chemistry): Flashcards

Energy absorbed during phase change at constant temperature

Hidden (energy hidden as no temperature change occurs)

Energy to change $1$ mole solid to liquid at melting point

Energy to change $1$ mole liquid to gas at boiling point

$6.0 \text{ kJ mol}^{-1}$

$40.7 \text{ kJ mol}^{-1}$

All hydrogen bonds must be completely broken in vaporisation

$q = n \times L$

Strong hydrogen bonds between water molecules

Remains constant at melting point or boiling point
