Question

exothermic and endo​

Answer 1

Answer:

A quick difference between endothermic and exothermic involves reactions in the environment. An endothermic reaction takes place when energy is absorbed from surroundings in the form of heat, and exothermic is when energy is released from the system into the surroundings. Both terms are mostly used in science and chemistry, but there are everyday examples as well.

Answer 2

Answer:

Many chemical reactions release energy in the form of heat, light, or sound. ... When endothermic reactions absorb energy, a temperature drop is measured during the reaction. Endothermic reactions are characterized by positive heat flow (into the reaction) and an increase in enthalpy (+ΔH).
