Is diffusion endothermic or exothermic

WebEndothermic - Heat is a product in the reaction. Endothermic The reaction mixture feels warm from the outside. Exothermic Determine whether each description corresponds to an endothermic reaction or an exothermic reaction. Heat is a reactant in the reaction. Exothermic The reaction mixture feels cool from the outside. WebAn exothermic process releases heat, causing the temperature of the immediate surroundings to rise. An endothermic process absorbs heat and cools the surroundings.” Based on the above definition, let's pick a few examples from our daily lives and categorize them as …

If it's true, then what's the reason behind it? Is it due to the fact that the latent heat of vaporisation of the Ammonia is added to the gross enthalpy of the mixture and that's why the temperature rises? If that's true then it's true for other gas/vapour too. crisi settore alimentare
