- What happens when cold air and hot air mix with each other?
Hot air and cold air dont usually collide; hot air rises while cold air sinks, thus separating the two They occasionally may collide, though Usually this results in some kind of precipitation
- Why does a hot air balloon need ballast? - Answers

- How does a hot air balloon come down? - Answers
A hot air balloon can descend by either releasing hot air from the balloon envelope or by opening a vent at the top of the balloon to allow some of the hot air to escape
- What type of heat transfer causes heat to rise and cold air . . . - Answers
