Aballoon flies forward when air quickly escapes it which law

I believe that that is Newton’s 3rd Law: for every action, there is an equal and opposite reaction. The molecules hitting the inside of the balloon cause it to propel forward.

Evaporation: this is when warmth from the sun causes water from oceans, lakes, streams, ice and soils to rise into the air and turn into water vapour (gas). water vapour droplets join together to make clouds! condensation: this is when water vapour in the air cools down and turns back into liquid water.
