Answer:
In chemistry, evolution of gas refers to the chemical reaction that has one of its end product as gas.
Like in photosynthesis, green plants uses sunlight, chlorophyll, water and carbon dioxide to prepare their food.
This is a chemical reaction in which light energy is converted into chemical energy.
The end products of photosynthesis are glucose that is the food and oxygen, hence gas evolution occurs.
