Answer:
the pressure is raised and the temperature is lowered
Step-by-step explanation:
According to the ideal gas law, there is no interaction between the molecules of an ideal gas. This implies that the molecules of an ideal gas are largely separated from each other and move around at great velocities in the vessel.
However, when the pressure is raised, molecules come into closer proximity with each other, similarly, when the temperature is lowered, the average kinetic energy of gas molecules is also lowered and intermolecular interaction become significant under these conditions. Hence, the ideal gas law now become inaccurate.
