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.
When a process releases energy into the surroundings it's called exothermic (from the Greek thermo meaning heat, and exo meaning outside). The most obvious effect of an exothermic chemical reaction is a rise in the temperature of the reaction mixture.
