100 POINTS! What happens when a reaction releases thermal energy?

How does a glow stick give off light?

Compare exothermic and endothermic reactions.

Classify the reaction of photosynthesis as exothermic or endothermic. Justify your answer.

1. Release heat and light into their surroundings.

2.Glow sticks emit light when two chemicals are mixed for example mixing the peroxide and phenly create the chemical reaccion making colors or glow

3. the diference betwen exothermic and endothermic reactions is the realise of energy in a form of sound, light, cold or maybe heat, so that means that the endothermic reactions absorb energy from the surrounding that is in the form of heat.

4. Endothermic and exothermic reactions are chemical reactions that absorb and release heat, respectively. A good example of an endothermic reaction is photosynthesis. Combustion is an example of an exothermic reaction

Explanation:

zfoods? ok, pressure is used to keep the heat inside and to keep the food perfect.
