Question

Equal volume of all gases contain equal numbers of molecules under similar conditions of temperature and pressure.
If true enter 1 , else enter 0.

Answer 1

The given statement is based on the law given by the Avogadro. If you know that law properly and thoroughly, then you can easily answer the given statement. Now solve it.

Complete step by step answer:
- First of all, let’s about the gases. Gases represent the state of matter in which all the particles are very loosely arranged and they do not have any fixed and definite shape.
- The molecules of the gases are in constant random motion and can freely move in any direction and have very high velocity and thus, in turn, have very high kinetic energy.
Now considering the statement as;
- This statement is based on the law which is given by Avogadro and hence the law is known as the Avogadro’s law.
- Avogadro’s law states that one mole of the gases under the similar conditions of the temperature and pressure i.e. 1 atmosphere pressure and 273 Kelvin temperature, contains Avogadro’s number of particles i.e. $6.023\times {{10}^{23}}$ and occupies the volume of 22.4 liters.
- Hence, the given statement that Equal volume of all gases contain equal number of molecules under similar conditions of temperature and pressure is true.
The correct option is “1” .

Note: Mole tells us about the quantity of the substance. It can be in the form of either particles, atoms, molecules, Avogadro’ number or volume and always remember that the Avogadro’s law is applicable on the standard conditions of the temperature and pressure.
