Agas with constant temperature has a pressure of 123 kpa and a volume of 123.13 l. a pressure change caused the volume to decrease to 28.15 l. what is the new pressure?

T = const.

P1 = 123 kPa

V1 = 123.13 L

V2 = 28.15 L

P2 = ?

This is an example of Boyle’s law which describes how the pressure of a gas tends to increase as the volume of the container decreases, meaning that P*V=const. For comparing the same substance under two different sets of conditions, the law can be expressed as P1*V1=P2*V2

P2=P1V1/V2

P2=123kPa*123.13L/28.15 L

P2=538.01 kPa

many phylogenetic trees have a single lineage at the base representing a common ancestor. a lineage that evolved early from the root and remains unbranched is called basal taxon. when two lineages stem from the same branch point, they are called sister taxa.
