If we were to fill a bottle with boiling hot water than place it in a bucket filled with cold water what would happen to the bottle and why?
i know the bottle would get crushed inwards but whats the science behind this can someone explain?

Water gas condenses to water liquid resulting in fewer molecules of gas and thus lower pressure. Since the atmospheric pressure is unchanged, the higher atm pressure pushes in on the walls of the bottle to compensate for the reduced pressure. Combination of charles law (condensation) and boyles law (decreasing volume - crushing of bottle to smaller volume - compensates for the condensation of water gas to liquid water. If the bottle volume did not decrease the pressure inside the bottle would decrease to well below the outside atmospheric pressure.
