Does the phosphorus cycle include the atmosphere?
no it does not include the atmosphere
Why cant airplanes fly straight out of the atmosphere?
Airplanes use air for lift and for thrust. If there's no atmosphere, they can't fly. Even a jet engine needs to burn and compress air.
What is most of the air in the air in the atmosphere made up of?
what is most of the air in the atmosphere made up of
Does a comet burn when it enters the earth atmosphere?
Yes
Where in the atmosphere do hot air balloons float?
Hot air balloons float because hot air displaces cool air in the atmosphere
Which metal burns in air?
Sodium, Potassium, and Phosphorus all burn upon contact with air.
Name the metal that can be burn in absence of air?
This is a badly worded question, I believe "burning" requires the oxygen in air. Substances such as Phosphorus react with air to burn, and may continue this reaction when submerged. But I do not believe this is what you mean
Is phospherous abundant in the atmosphere?
Phosphorus is not a component of the atmosphere.
Does the phosphorus cycle include the atmosphere?
no it does not include the atmosphere
Does white phosphorus burn easily?
White phosphorus is very flammable.
Is phosphorus cycled through the earths atmosphere?
phosphorus is not cycled through the earth's atmosphere
How does carbon and nitrogen affect the atmosphere?
Carbon affects the atmosphere when humans burn fossil fuels into the air and other chemicals
Is phosphorus abundant in the atmosphere?
Yes.
What is the only biogeochemical cycle which does not pass through the atmosphere?
Phosphorus. "Unlike many other biogeochemical cycles, the atmosphere does not play a significant role in the movement of phosphorus, because phosphorus and phosphorus-based compounds are usually solids at the typical ranges of temperature and pressure found on Earth." - However, phosphorus WILL cycle through organisms and water. Water does (evaporation and precipitation both include the atmosphere). Carbon does (carbon dioxide is the third most common substance in the atmosphere). Nitrogen does (nitrogen makes up most of the atmosphere; Nitrogen-fixers depend on this fact).
Which point does phosphorus catch fire?
Red phosphorus burn at approx. 200 0C.
What is used in matchstick that it makes it burn?
phosphorus
Why phosporus kept in water?
Potassium is a soft metal which reacts violently (spontaniously combusts) with both water and oxygen, so both must be excluded, by storing it in paraffin or kerosene. Phosphorus is a non metal .White phosphorous is kept under water because it reacts with oxygen but not water. Red phosphorus (the allotropic form P4, which occurs when white phosphorus is heated above 275`C) is more inert and does not need to be kept in water to exclude air.
