when we take a bath the mirror has on it some gas, the steam on the sauna, and maybe fire
Condensation is a purely physical process (a change of phase). Water evaporating or condensing does not change its molecular composition (H2O).
the answer is condensing edit: condensation
a very cloudy sky
heat released from condensing water vapor
exothermic
Dew and rain are two examples.
water condensing is a physical change.
The water vapour is condensing.
Condensing
The condensing of water vapor in to water dropplets
At the cloud base when water vapor begins condensing it begins to release it. This releasing is called rain.
The condensing point is the particular temperature at which a substance changes state from gas to liquid. The condensing point of water is 100 deg. C or 212 deg. F.
fog
Its still water.
Physical. It was water before condensing, and it is water after. All that changed is energy was lost that allowed a phase change.
chilled water
Water is condensed on a cool surface.
