Avogadro's law and charles's law describe a proportionality of the volume of a gas when the pressure is constant. which
describes the proportionality that allows these laws to be combined when describing a gas?
volume is directly proportional to temperature (avogadro's law) and to moles (charles's law).
volume is inversely proportional to temperature (avogadro's law) and to moles (charles's law).

a saline water is fed to a reverse osmosis unit at flow rate o rotameter connected to reject (retentate) line reads 8 installed in reject and permeate line reads 15.2 milli siemens/cm and 300 micro siemens/com respectively.

each chemical family is represented as a group or column on the periodic table. based on chemical properties, there are 6 types of chemical families. group 1 represents alkali metals, group 2 represents alkaline earth metals, groups 3 to 12 represent transition metals, groups 13 to 16 represent non-metals and other metals, group 17 represents halogens and group 18 represents noble gases.
