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.
Respiration is a pure exothermic reaction because when we exhale there us carbon dioxide along with the residual oxygen and with certain amount of water vapour. No heat energy is provided during inhalation however the energy or heat liberated during oxidation of the food and other activities comes out as heat energy. Since there is heat energy released during respiration the reaction is called to be the exothermic reaction.
