The process of making camphor vapor from solid camphor is called sublimation. Sublimation is the direct transition of a substance from its solid phase to its gas phase without passing through the liquid phase. When solid camphor is heated, it ...
Dew is not formed on a strong windy night because the rate of evaporation is fast. The movement of air removes the thin layer of moisture near the ground, preventing dew formation.
It takes more time to cook potatoes on mountain tops because atmospheric pressure is low. At higher altitudes, the reduced atmospheric pressure lowers the boiling point of water, causing water to boil at temperatures lower than at sea level. This ...
The reason why snow covered on mountains does not melt simultaneously due to the heat of the Sun is because it reflects most of the heat received from the Sun. The reflective properties of snow prevent it from absorbing much ...
