On what factors do the values of the gas constant $R$ depend? What is its unit?

At constant temperature and pressure,what is the volume of $n$ moles of different gases?

If $2.5$ moles of an ideal gas at a certain temperature are allowed to expand isothermally and reversibly from an initial volume of $2$ $dm^3$ to $20$ $dm^3$, the work done by the gas is $-16.5$ $kJ$. The temperature (in $K$) of the gas is (Round off to the nearest value). $(R = 8.314 \ J \ K^{-1} \ mol^{-1})$

The graph of $V$ versus $T$ for an ideal gas at constant pressures $P_1$ and $P_2$ is shown below. Which of the following is correct?

"Equal volumes of all gases at the same temperature and pressure contain equal number of particles." This statement is a direct consequence of

Explain the relationship between pressure,volume,and density of gases.
