Heat is evolved diving
WebChemical reactions are mostly accompanied by a change in heat, An Exothermic reaction is a chemical reaction in which heat is evolved. Eg- combustion of fuels, some polymerization reactions, decomposition of organic waste, etc. An Endothermic reaction is a chemical reaction in which heat is absorbed. Eg- melting of ice, evaporation of liquid ... WebThe dive profile of Toby, a translocated juvenile northern elephant seal (Mirounga angustirostris), with the color indicating the direction of heat flux (red = heat gain, blue = heat loss) throughout the dive. The inset shows four deep dives (>200 m) and how the transition from heat gain to heat loss occurs near the thermocline (denoted with ...
