Endothermic and Exothermic
Answer (1)
Endothermic and exothermic reactions are two significant categories of energy changes. Whether heat is absorbed or released during the reaction is described by these terms. Exothermic reactions emit heat into the environment, whereas endothermic reactions absorb it. Knowing the distinction between the two enables us to explain commonplace occurrences such as the melting of ice or the warming sensation of a fire.Exothermic ReactionHeat is released (energy is released).The temperature rises.Examples:Combustion (burning)Rusting of ironCondensation of steamFreezing waterEndothermic ReactionHeat is absorbed (energy goes in).Surroundings get cooler.Examples:PhotosynthesisCooking an eggMelting iceBoiling waterTo quickly remember, or distinguish both Exothermic and Endothermic Reaction—you can take note of this:Exo means exit (heat exits)Endo means enter (heat enters)
