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.
Digestion of food releasing energy = exothermic reaction. Melting ice absorbing energy = endothermic reaction. Exothermic releases energy. Endothermic absorbs energy. That is the difference. The example you have given with sodium and chlorine gas is generating heat, (releasing energy) which makes it exothermic. it's not explosive...cold water and sodium is explosive...it's exothermic because heat is coming out...and endothermic is when you have to provide heat...e.g.
