Plants use only carbon dioxide gas from the air, water and sunlight.

Two of the small canisters contain only carbon dioxide gas.

As expected, the mass was less (carbon dioxide gas escaped).

But there was no inrush of hot carbon dioxide gas.

Outward pressure of the carbon dioxide gas causes the rising effect.

We put out a flame with the carbon dioxide gas.

They react when dissolved in water to make carbon dioxide gas.

Natural carbon dioxide gas also rises from separate pockets below the water.

Both the water and natural carbon dioxide gas are captured independently.

Doing something that burns fuel will make carbon dioxide gas in the smoke.
