Plant's produce oxygen, to explain this you would state that the plant uses CO2 from the air and removes the carbon and then release breathable O2 into the atmosphere. To test this you could use a small fern and put it in a sealed container of some kind big enough to hold it, then add a burning candle in the container with the plant, since we know fire burms O2 and creates CO2 the plant should use the CO2 and create more O2 keeping the fire from burning out from lack of oxygen
A denser liquid will sink to the bottom while a less denser liquid will float. Also, liquids composed of polar molecules such a water will not form chemical <span>bonds with nonpolar molecules.
Density.

To solve this problem we will apply the concepts related to the balance of forces. Said balance will be given between buoyancy force and weight, both described as derived from Newton's second law, are given as
Buoyancy force
Here,
V = Volume
=Density of air
g = Acceleration due to gravity
Weight
m = mass
g = Gravity
Our values are given as,
Then,
Replacing,
Now net force is ,
Mass of the sphere is
Now acceleration of the sphere is
Therefore the acceleration of the sphere as it falls through water is 
<span>It is measured in calories </span>
The object that had the most 1000 ton weight has the most momentum
