1 inside and outside forces acting on the bottle are equal normal shape



the forces acting on the outside is greater than the inside the force is called air pressure







2  Hot    force acting on the inside is greater than the force acting on the outside
bottle bulges


3  hot water emptied lid on cool under cold water
bottle collapsed
force acting on outside of bottle is greater than force acting inside
why

air is made up of nitrogen,oxygen and carbon dioxide
why
Air pressure( Aforce) is greater
Air particles have more energy and push harder against bottle
