Question

Please do not use Z in your answer as the main answer, onlyuse it to explain.

When the pressure calculated by the ideal gas law is larger thanthe pressure calculated by VdW for a real gas, are the gasparticles in the repulsive region or the attractive region?

When the pressure calculated by the ideal gas law issmaller than the pressure calculated by VdW for a real gas, are thegas particles in the repulsive region or the attractiveregion?

When the pressure calculated by the ideal gas law isequal to the pressure calculated by VdW for a real gas, are the gasparticles in the repulsive region or the attractiveregion?

When the volume calculated by the ideal gas law islarger than the volume calculated by VdW for a real gas, are thegas particles in the repulsive region or the attractiveregion?
