Gas and Gas Laws Question


In an inert real gas, when the pressure is increased (doubled), the volume decreases, but not all the way down to 1/2 of the original value. The new volume would be 1/2 Vi + a little bit. I know this has to do with Van Der Waals and accounting for the corrections for a real gas, but why is the new volume a little bit greater than 1/2? I am finding it difficult to get an intuitive sense for this.
