Positioned as the de facto standard for next-generation flame-retardant PBT resin, the product complies with the world safety and environmental standards, employing a non-halogen flame retardant to achieve the highest V0 retardant level set by the Underwiters Laboratories.
2. EXPERT ANSWER. Evaporation is an endothermic process. The reaction in which heat is absorbed by the system is known as endothermic reaction. In evaporation heat is absorbed and passed to the water which forms vapor when heated. Posted by Krishnakoli Datta on 30/5/13.
Evaporation is the phase change of a liquid to the gas state. Evaporation is one of the two types of vaporization. The other form of vaporization is boiling. Evaporation occurs only on the surface of the liquid. When the energy of such a surface liquid molecule is increased due to any internal or external factor, the molecule will be able to break the intermolecular bonds acting on it, thus creating a gas molecule. This process can occur is any temperature.
