What is the reason for paper getting stuck to a hot bowl when it is kept on paper for a certain period . I hve seen particularly that newspaper when placed under a hot bowl gets stuck to the bottom of bowl when the bowl is lifted ?

I think the cohesive forces b/w the the two surfaces must playing some part but at high temp shudn't the magnitude of force b/w the two be less due to thermal agitation.

I don't know if this is the correct answer in your situation, but my experience is that the paper frequently becomes damp. In that case, it would be the surface tension of the water causing adhesion.
