Did you know?
WebEndothermic reactions require energy, so energy is a reactant. Heat flows from the surroundings to the system (reaction mixture) and the energy of the system increases. … Web8 sep. 2024 · Energy absorbed by a body is directly proportional to the rise in temperature of a body. Heat energy absorbed by a body is directly proportional to the mass of the body. Heat energy absorbed by a body depends upon its nature and is commonly called specific heat capacity. How do you calculate heat absorbed by a calorimeter?
Web7 jul. 2024 · In endothermic reactions, more energy is absorbed when the bonds in the reactants are broken than is released when new bonds are formed in the products. Endothermic reactions are accompanied by a decrease in temperature of the reaction mixture. What happens when a chemical reaction absorbs heat energy?
