Цель опыта проверим предположение что кислород поддерживает горение углекислый возьмё два сосуда в один поместим проросшие семена с другой стороны поместим суда проросшие семена на кроем крышками через день или два в каждый сосуд опустисгорящую свечу В каком сосуде свеча погаснет

Answer 1

Где семена не проросли, так как огонь горит благодоря кислороду!

Answer 2

Experiment to Test the Role of Oxygen in Sustaining Combustion

To test the hypothesis that oxygen sustains combustion, an experiment can be conducted using two vessels. In one vessel, we will place germinated seeds, and in the other vessel, we will place germinated seeds covered with lids. After a day or two, a burning candle will be lowered into each vessel to observe the outcome.

The purpose of this experiment is to observe whether the presence of oxygen affects the sustenance of combustion. By comparing the results from the vessel with open access to oxygen (seeds only) and the vessel with restricted access to oxygen (seeds covered with lids), we can draw conclusions about the role of oxygen in sustaining combustion.

Expected Outcome

The burning candle in the vessel with open access to oxygen (seeds only) is expected to continue burning, while the candle in the vessel with restricted access to oxygen (seeds covered with lids) is expected to extinguish.

Conclusion

The results of this experiment will provide insights into the role of oxygen in sustaining combustion. If the expected outcome aligns with the hypothesis, it would support the notion that oxygen is essential for combustion to continue.
