Question

According to Avogadro’s law what happens to the same temperature and pressure?

Answer 1

Hint : We can call the Avogadro law by the other names also such as Avogadro’s hypothesis or Avogadro-Ampere’s hypothesis or Avogadro’s principle. To answer this question we should have a basic knowledge about this law like its applications, its limitations, its properties, etc.

Complete Step By Step Answer:
Avogadro’s law can be defined as or states that “the equal volume of all the gases, at the same temperature and pressure, will have the same number of molecules”. This law is applicable to ideal gas only. It means that if the gas is ideal, then the same number of molecules exists in the system. If the volume of the gas is equal it means that the number of molecules will be the same as that of an ideal gas when it also has an equal volume. The mathematical expression of above statement is: $\dfrac{V}{n} = cons\tan t$ or we can also say that $\dfrac{{{V_1}}}{{{n_1}}} = \dfrac{{{V_2}}}{{{n_2}}}$ where V is the volume of an ideal gas and n is the number of molecules.

Note :
From above we can see that this law can also be known as a specific case of an ideal gas law. This law was given by the scientist named Amedeo Avogadro in $1812$ . We can also give the example to illustrate this law and that example is equal volumes of hydrogen and nitrogen contains the same number of atoms at the same temperature and pressure as well.
