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 a cooling process--each molecule lost lowers the energy of the remaining molecules Atmospheric Pressure acts as solid lid to evaporating liquid. Once Evaporation-Condensation Equilibrium is reached, the pressure that the gas exerts over the liquid is the Vapor Pressure of the liquid.
