Why a tightly fitting cork on a test tube is blown off if the test tube is heated?
The air molecules inside the test tube have a higher mobility when heated (they move around more). The collisions between these air molecules create more pressure on the inside of the test tube (force/area, where the force is the result of the increasing collisons and the area is the internal wall of the test tube.) This may result in the pressure inside of the test tube to be greater than the outside atmospheric pressure on the cork (actually atmospheric pressure on the cork and the frictional force on the cork created by the mouth of the test tube). If the internal pressure becomes greater than the external pressure (plus frictional force) the cork will come loose of the test tube.
