प्रश्न
Give reasons:
A gas fills completely the vessel in which it is kept.
उत्तर
- The kinetic energy in a gas is maximum due to the low force of attraction between the particles in which it is kept.
- The gas particles are constantly travelling in all directions at different speeds.
- As a result, they have no definite volume and, hence, completely fill the vessel in which they are kept.

The substance X normally exists in a physical state which can flow easily but does not fill its vessel completely. It also turns anhydrous copper sulphate blue. When substance X is cooled excessively, it changes into a substance Y which has a fixed shape as well as a fixed volume. If, however, the substance X is heated strongly, it changes into a substance Z which has neither a fixed shape nor a fixed volume.
