Question

why always candle flame upwards​

Answer 1

Answer:

Hey mate

Here is your answer.

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.

Hope it helps you.

If it does then please mark as brainliest.

Answer 2

Answer:

When you start a fire, fuel combines with oxygen to release heat, light, carbon dioxide, water vapor, soot etc. The heat energy generated in this process heats up the air around the flame which in turn reduces its density.

This hot air around the flame then starts rising up and the surrounding colder heavier air rushes down into its place accelerating the hot air upwards which in turn causes the flame to shoot up
