Nothing. It's still a gas. The fizz when you open a can is carbon dioxide.
Nothing happens. It has to be compressed to 5.13 atmospheres before it turns solid at -56.4°C.
The atmospheric pressure reduces
intrapleural pressure exceeds atmospheric pressure, but lungs don't collapse because intra-alveolar pressure increases, too (4 mmHg pressure gradient stays same)
atmospheric
On a windy day atmospheric pressure decreases because the higher the wind velocity, the lower the air pressure, or atmospheric pressure. This is how chimneys work, the air that moves above the chimney causes low air pressure because of the high wind velocity compared the velocity of the air inside a house. The air inside the house goes towards the low air pressure and takes the smoke with it.
This would actually be a simple answer: Pressure decreases. Simply because of the fact that as altitude increases, the less air there is on top of you, and the lower the pressure would be.
It is compressed and occupies a smaller volume.
When a parcel of air is forced downward, atmospheric pressure increases, causing the air to become compressed and therefore the temperature is also raised.
The CO2 is diffused back into the alveoli, where, by the diaphragm, is pushed back into the environment by atmospheric pressure.

it decreases
it dies
Carbon Dioxide, under pressure and cooled, becomes 'Dry Ice'. It takes on the appearance of a block of frozen water (ice).
Its vapor pressure equals atmospheric pressure.
The atmospheric temperature will decrease
The atmospheric pressure reduces
Atmospheric pressure falls
As altitude above seal level increases, atmospheric pressure decreases.
