Describe the processes involved when water changes to ice through the unstable
supercooled stage to the stable solid state.
Explain the importance of heat energy (expressed in joules) in the process of changing
the temperature of water, and changing the state of water.

Explain the effect on the height of the freezing level when stable saturated air or
unstable saturated air is lifted orographically.
State the: (a) potential for ice accretion in the 10 main cloud types and in lenticular cloud;
State the: (b) type of ice to be expected in each cloud type;
