The composition of air depends upon altitude.
The composition is the same, the air is just less dense.
No, inflating a bike tire is a physical change because it does not change the chemical composition of the tire or the air being pumped into it. When air is added to the tire, it simply increases in volume and pressure without altering its chemical properties.
Air is compressible, meaning its volume can change in response to changes in pressure.
The change in volume from gaseous air to liquid air is about 1/600th of the original volume. This significant reduction in volume is due to the compressibility of gases at high pressures and low temperatures during the liquefaction process.
Whisking egg whites is a physical change, not a chemical change. Whisking simply incorporates air into the egg whites, changing their texture and volume without altering their chemical composition.
Ofcourse, the volume will increase Ofcourse, the volume will increase
Yes, the volume of air can change based on factors such as temperature, pressure, and the presence of other gases. When air is heated, it expands and its volume increases. Conversely, when air is cooled, it contracts and its volume decreases.
yes, the air becomes less dense and there is less oxygen
Inflating a basketball with an air pump is a physical change because it does not involve any change in the chemical composition of the materials involved. The air is simply being forced into the ball, causing it to expand and increase in volume, but the fundamental chemical makeup of the ball remains the same.
if the dna sequence of a gene was tacttaccgagctagact then what kind of mutation has occured This has nothing to do with the question of air pressure. Either a change of temperature or a change of volume can affect air pressure, according to Boyle's Law of Gases. Increasing temperature=increased air pressure Decreased volume=increased air pressure The reverse is also true. Decreased temperature=decreased air pressure Increased volume=decreased air pressure
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.
