Two identical containers fitted with pistons hold equal numbers of gas molecules at the same temperature. One container holds a gas that behaves as an ideal gas; the other holds a real gas, in which the molecules occupy a significant volume and attract one another. Compare the pressures exerted by the two gases. In your answer, explain how the pressure of a gas arises, and state and explain how the pressure of the real gas compares with that of the ideal gas when (i) the pistons are pushed in so that both gases occupy a very small volume, and (ii) the containers are cooled to a very low temperature at constant volume.
