How does a ballon defeating slowly support the particle model
As the warmer air inside the balloon cools, the balloon will shrink slightly. The amount of shrinkage will depend on the temperature change.

The heat from the lighter, when placed on the surface of the stretched surface of the balloon,would melt the plastic of the balloon and allow the air inside the balloon to escape, so deflating the balloon.

An ice cube melting, a candle burning down, and a balloon deflating are examples of things that get smaller as time passes.

At the end of a hot air balloon flight the heated air inside is allowed to escape through a panel that is opened either in the top or side of the balloon envelope. The crew then squeezes the remaining air our of the envelope and then packs it away in a large bag ready for the next flight. This process is called deflating the balloon

Evaporation is not a phase change form i is a process by which phase change.
Yes, it is a physical change. Nothing chemically changed about the balloon.
