To prove that a certain fruit (in this case, an orange) indeed contains a certain compound (in this case, vitamin C); then the vitamin C should be extracted and isolated from the orange and must be confirmed by molecular analysis. The extraction process involves using chemicals (i.e. 6% MPA), and procedures such as centrifugation and filtration. Then the extract is stored and subjected to high-performance liquid analysis (HPLC) to measure the vitamin C content.
It could be cooled which would then cause it to become over-saturated resulting in condensation that would return the air to a saturated state. Over-saturated air, with a humidity greater than 100%, is unstable, causing changes to restore stability. Hope this helps!
Death rate is lower than birth rate, and immigration equals emigration would lead to an increasing population.
