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 ...
Sublimate substances, such as camphor, naphthalene, and ammonium chloride, transition directly from solid to vapor phase. These substances exhibit sublimation behavior, seen in various applications like mothballs, vaporizers, and laboratory processes.
The transformation of a solid substance directly into vapor state without changing into liquid is called sublimation. Sublimation is a phase transition where a solid substance bypasses the liquid phase and converts into vapor upon heating, or vapor converts directly ...
Cryogenic testing is conducted at extremely low temperatures, typically around -196 °C. These temperatures are necessary for handling and testing materials and equipment that are intended for use in cryogenic applications, such as rocket engines, superconductors, and other low-temperature technologies.
Boiling is the process where a substance changes from its liquid state to vapor state throughout the bulk of the liquid, typically occurring at a specific temperature called the boiling point.
The most appropriate color combination of umbrellas for protection from the sun is White above and black below. White reflects sunlight and heat, keeping the area beneath the umbrella cooler, while black absorbs heat, preventing it from reaching the user. ...
Clothes keep us warm in winter because they prevent body heat from going out. In cold weather, our bodies generate heat through metabolic processes. Clothing acts as insulation, trapping this heat close to the body and forming a barrier against ...
