If $P,V,M, T \mathrm{and} R$ are pressure, volume, molar mass, temperature and gas constant respectively, then for an ideal gas, the density is given by

Arrange the following relevant points in a proper sequence for explaining why Kelvin scale is preferred to Celsius scale in the study of gases.

1. $-273°\mathrm{C}$ is the least possible temperature.
2. A graph of volume vs temperature is a straight line passing through origin.
3. A graph of volume vs temperature $\left(0°\mathrm{C}\right)$ is a straight line which intersects volume axis at some point.
4. Extrapolation of straight line touches the volume axis at$-273°\mathrm{C}$.
5. $-273°\mathrm{C}$ is called absolute zero or $0 \mathrm{K}$.
6. All values of temperature are positive in Kelvin scale.
7. Usage of negative values for temperature gives negative values for other properties like pressure and volume.
