Write the observations of priestleys experiment |

Answer» tion: the course of these experiments, Priestley made an enormously important observation. A FLAME went out when placed in a jar in which a mouse would die due to LACK of air. Putting a green plant in the jar and exposing it to sunlight would "refresh" the air, permitting a flame to burn and a mouse to breathe. Perhaps, Priestley wrote, "the injury which is CONTINUALLY done by such a large number of animals is, in part at least, REPAIRED by the vegetable creation." Thus he observed that plants release oxygen into the air — the process known to us as photosynthesis. |
