Question

When we pour a bottle with hot water up tp the brim then does bottle shrink
Because in all experiments we keep bottles half empty so that steam inside condenses and bottle gets crushed
So i want that whole to be filled not half filled
Pls ans the quest by explaining concept in easy way

Answer 1

Consider two process, which have contributed to collapses the bottle. In the first case, the bottle is a thermoplastic. When we pour a bottle with hot water the plastic becomes more plastic, and will deform. In the second case, the hot water made steam. The pressure inside the bottle becomes less than atmospheric pressure. The bottle is destroyed due to the pressure difference.
