Phase Changes
Solids can...Turn to liquid by Fusion (Melting)
Turn to gas by Sublimation |
|
Each of these processes can either give off heat (ΔH negative) or absorb heat (ΔH positive)
When solids melt, the intermolecular forces are overcome and the molecules can break apart from each other.
When liquids boil, the intermolecular forces are being overcome and the free molecules can float around in space.
All phase changes are directly related to intermolecular forces.
