Factors affecting plant photosynthesis: light intensity
Applicable Academic Stage：
Junior high school biology
Determine the oxygen content in the air. Red phosphorus combustion consumes the oxygen in the collecting cylinder, making the pressure in the cylinder less than the outside atmospheric pressure, water will flow back from the beaker into the collecting cylinder, and the volume of the backflow water is the volume of oxygen in the air.
