Question

V α n At Constant T and P, the statement is based upon​

Answer 1

$V$∝ $n$ at constant $T$ and $P$ , the statement is based upon Avogadro's Law.

• The law which gives the relation between the volume of gas and the number of moles present in it is known as Avogadro's law.
• According to the law, the volume of gas is proportional to the number of moles when the condition of temperature and pressure remains constant.    
• It can also be stated as the equal volume of all gases under the same conditions of temperature and pressure contains the same number of moles of molecules.
• $\frac{V}{n}=constant$
