Give reasons for the following:
It is necessary to specify the pressure and temperature of gas while stating its volume.

उत्तर
At a given temperature, the number of molecules of gas striking against the walls of the container per unit time per unit area is the same. Thus, gases exert the same pressure in all directions.
Because the volume of a gas changes remarkably with a change in temperature and pressure, it becomes necessary to choose a standard value of temperature pressure.
