When we light a match stick, the flame always will be pointed towards the upper side.why?

Answer 1

Heated gas is lighter than the same amount of cold gas. Therefore it rises up. Its place is taken up by the surrounding cold gas which also rises if it is being continuously heated. This process is called convection. You would also realise that convection occurs in our world because we have gravity. Without gravity nothing can be lighter or heavier because there is no weight! In a space capsule in orbit the candle flame would not know which way to point. Indeed there would be no flames as we know them in our ordinary world.

Answer 2

When a match stick is heated the air surrounding it burns .
Thus the air nearby gets heated up and so a pressure difference is created .The region around the of flame experiences a low pressure and high pressure below it .
Thus the flame rises from high to low pressure region.
So the flame rises up.

Answer 3

for this, you have to understand some points.
flame of any substance when burnt will always point upwards because, when a substance is burnt, the temperature of the substance rises. also, by process of radiation, the surrounding temperature near the root of the flame rises. as a result, the surrounding air temperature also rises. as hot air is lighter than cold air and layer of hot air rises up leaving behond the cold air, and as this is a continuous process as long as the substance is burning, it appears as if the flame is pointed upwards.

Answer 4

once you have combustion, alongside with a experience or a candle, what happens is that oxygen gets fed on, and different gases (alongside with carbon dioxide) get produced. as properly, of direction, power is liberated interior the type of warmth and mild-weight. The produced gases are warmer than the surroundings by way of generated power, and that they amplify, as heated gases do. Then, of direction, in view that their density is below the encompassing environment, the gas has a tendency to upward push. This has 2 effects. First, on a similar time because it strikes up, it consists of power with it, subsequently the flame finally ends up pointing "up". 2d, by way of fact the products of combustion pass up, they make greater oxygen available to make the flame proceed to burn.

Answer 5

What kinda idiot lights matches in the space shuttle to find this out? Does this mean then that if we increase gravity the flame will go down instead of up?

Answer 6

Because hot air goes up. This doesn't work if there is no gravity, so in the shuttle a flame is spheric.

Answer 7

The reason is gravity..

Answer 8

when you light a mstch stick, the O2 near the stick uses to bur itself creating a empty space, added to that the hot surrounding pushes it up as the cold air is dense.

Answer 9

nitrogen gas present in the smoke of the flame

Answer 10

as light gases(hot gases) tend to rise with that the flame also tends to rise.
