A balloon filled with helium does not rise in air indefinitely but halts after a certain height. (Neglect winds). Explain

A balloon filled with helium does not rise in air indefinitely, but halts after a certain height. Why ?

Why does a balloon filled with hot air rise upward in air?

A balloon filled with air, when kept in sunlight bursts after some time. b) Justify.

A balloon filled with air, when kept in sunlight bursts after some time. a) Name the related law.

A baloon filled with helium rises against gravity increasing its potential energy. The speed of the baloon also increases as it rises. How do you reconcile this with the law of conservation of mechanical energy ? You can neglect viscous drag of air and assume that density of air is constant.
