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.
in all exothermic reactions the reactants will have higher energy than the products. the answer is pretty much the same as why freezing is an exothermic reaction-- because the release of energy is occurring as bonds are forming. to form bonds, energy must be inputted or it won't happen naturally.
