Carbon dioxide and water vapor rise above the flame because they are products of combustion that have higher temperatures and lower densities than the surrounding air. This causes them to be buoyant and therefore they rise upwards above the flame.
In a gravitational field, flames usually burn upwards because the hot gases in the flames are less dense than the surrounding gases, hence buoyant forces cause the hot, luminous gases (which we see as the flame) to rise. In a zero gravity environment, the direction of the flame is not necessarily "up" since "up" is arbitrary without a gravitational field.
A flame cannot be any cold but always hot even at the first instant it is lit.
The correct blended word for "flame" and "glare" that means to blaze up with bright flame is "flare." This term captures the essence of a bright, intense light or flame, often used to describe sudden bursts of fire or brightness.
Not all pajamas are flame resistant. It's always a good idea to check the product label for flame-resistant materials or information. Flame-resistant pajamas are typically designed to reduce the risk of burns in case of accidental exposure to fire.
Yes It. Is.
The flame burns "up" because it is really the hot gasses that are burning and hot gasses rise because they are less dense.
The heat generated by the fire warms surrounding gasses and they rise, pulling the flame up.
Carbon dioxide and water vapor rise above the flame because they are products of combustion that have higher temperatures and lower densities than the surrounding air. This causes them to be buoyant and therefore they rise upwards above the flame.
The air above and around the flame heats up, expands and moves up. Cooler air below the flame moves in to take its place, heats up, rises and the process repeats itself.
lets take the candle as an example: the flame of the candle heats the surrounding air thus the cold air bushes the hot air up and takes its place because the cold air is much denser than the hot air, due to this motion the flame itself goes up with the hot air and so on.
you can buy Flame Libra at target. but i wouldn't get to excited about it because target is almost always out of Flame Libras.
No, the presence of a continuous flame on oil drilling rigs depends on the specific equipment and processes being used. Some rigs may use a flare system to burn off excess gas or emissions, while others may not have a visible flame at all times.
You can't it is always the same. You only use the blue flame to heat things because the yellow flame is the safety flame and the blue flame is hotter.

1. not all elements give colour to the flame 2. flame test is not always accurate
