Question
Why flame is in always upward direction.
Open in App
Solution
A
candle flame points upwards because flame is extremely hot, and thus less dense
than air (by a routine approximation using the Ideal Gas Law), and thus rises.
A hot air ballon floats for the exact same reason. As mentioned in the
"possible duplicate" question, this effect disappears in the absence
of gravity
