Add one line to the graph to represent the expected relationship for the same amount of an ideal gas.
State and explain, with reference to the graph, which of $T_1$, $T_2$ or $T_3$ is the lowest temperature.
Explain your answer to (ii) with reference to intermolecular forces.
State and explain the effect of pressure on the extent to which a gas deviates from ideal behaviour.
A flask of volume $100\,\text{cm}^3$ was weighed once while it was filled with air and then again while it was filled with another gas, Y. The measurements, taken at $26^\circ\text{C}$ and $1.00 \times 10^5\,\text{Pa}$, are given below. Mass of flask containing air = $47.930\,\text{g}$. Mass of flask containing Y = $47.989\,\text{g}$. Density of air = $0.00118\,\text{g cm}^{-3}$. Calculate the relative molecular mass, $M_r$, of Y.
