Question

At what temperature the volume of a gas is supposed to be zero?

Answer 1

The explanation of temperature for zero volume occurrence is explained as:

1. According to Charle's law, the volume occupied by the gaseous molecules is directly proportional to the temperature.at constant pressure.
2. $$\begin{gathered} \mathrm{V}\mathrm{\alpha }\mathrm{T} \\ \mathrm{V}=\mathrm{kT} \end{gathered}$$
3. Below is the graph plotted using the above formula between volume and temperature.

In the above diagram if the line is hypothetically extrapolated in $-\mathrm{x}$ axis where the volume is $0$ on $\mathrm{y}$ axis, then the temperature comes out to be $-273.15°\mathrm{C}$ or $0\mathrm{K}$.

Therefore, the above points and diagram clearly explain that at $-273.15°\mathrm{C}$ or $0\mathrm{K}$, the volume of gas is supposed to be $0$.
