i think there would be less oxygen because the plants take in carbon dioxide and release oxygen
if the composition of the air would change if the dust would be replaced from nanophase ferric oxides
The composition of air depends upon altitude.
no
The composition is the same, the air is just less dense.
When a car is turned into a wreck, this involves a physical change because the molecular composition of the car doesn't change. After the crash it will still consist of steel, petrol, etc. However, if one was to set fire to the car, it would undergo a chemical change: its molecular composition would change because the molecules would bind with the oxygen molecules in the air.
yes, the air becomes less dense and there is less oxygen
The composition of the Earth's atmosphere (air) has changed over geological time. This change has been brought about by biological processes (life). The planets air is therefore part of the biosphere and any change in the air will be accompanied by biospheric changes.
Because cells consume 02 and release CO2 as waste. So the composition changes
Oil would prevent the plant from taking in air. The plant would die. When a plant is dormant, you can put dormant oil on them to kill insects.
Tornadoes do not produce gasses. They are made of air and do not change its composition.
Yes, liquefaction of air is a physical change because it does not involve any change in the chemical composition of the air molecules. It is a reversible process where the air transitions between gas and liquid states due to changes in temperature and pressure.
how heat would change the density of a parcel of air?
