Question

what happen when balloon put in cold water

Answer 1

Answer:

Gases always expand when they're warm - the heat gives the gas energy to spread out more). The expanding gas blows up the balloon. When you put the bottle into cold water, the air cools down again. Cool air hasn't got as much energy, so it shrinks - and the balloon shrinks with it.
