This is an interview question isn't it?

I don't know the answer but this would be my response...

Internal energy is the sum of kinetic and potential energy. If the interaction between the molecules disappear, the potential energy is gone. But it can't just disappear so it must be transferred into kinetic/rotational energy.

Which in turn would exert a greater force on the container? So pressure on container increases.
