Write short notes on exothermic and endothermic reactions oxidation reduction reaction oxidizing and reducing agents brainly
Answers
Answer:
When energy is released as heat, the process is exothermic, and when heat is absorbed, the process is endothermic. An endothermic reaction is one which results in a net decrease in temperature because it absorbs heat from the surroundings and stores the energy in the bonds formed in the reaction.
a process or reaction that releases energy from the system to its surroundings, usually in the form of heat, but also in a form of light, electricity, or sound.
Answer:
Answer:
exothermic process in which heat is given out .
endothermic process in which heat is absorbed:
Explanation:
when NaOH (solid )dissolves in water there is evolution of heat leading to rise in temperature
2.when KNO dissolves in water there is absorbed of heat during the reaction and the temperature of the solution falls.
