does a flame have any weight? if yes, how can it be measured?

Answer 1

Depends on the size......... the bigger it is, the heavier

Answer 2

Good question that got me thinking. I guess it does have a weight and it could be measured. If it could not be measured it does not necessarily have no weight. Assume one is trying to weigh the weight of a flame from a candle, somehow one has to keep the candle enclosed in a recipient and on a weighting devise. Now if the air in the recipient had been weight beforehand (by volume) and the gas emitted by the flame collected and weighted. Then one has to use add and subtract to reach a conclusion. For example how much the candle weighted in the first place how much it weighted after it burned to a certain size. The fumes would be weighted and added to the lost weight of the candle that way would leave the weight of the flame which I guess would be infinitesimally small and better done in an advanced lab.

Answer 3

First of all, what is flame? The burning process is a reaction between a matter that burns and the oxygen. It is an exotermic reaction, which means that when it occurs, the heat is emitted. So when something oxidizes rapidly, it causes a lot of heat in the area in which the reaction occurs. And this heat causes the burning and burnt matter (usually gas, smoke) to emit light. Just like when you heat up a metal pole to a sufficient temperature, it first turns red, then yellow, so is the case with burning products.

This means that a flame is basically a certain amount of gaseous matter that is hot enough to emit visible light. So if you can figure out a volume that is taken up by flame and the density of gas (smoke, burning gas, etc.) that takes up that volume, you can find the approximate (!) weight of that certain flame.

Answer 4

A flame has no weight.

A fire is an emission of energy that you can see as light and heat. Whatever the flame is burning has weight, and if there is smoke, there is mass in that too, but the fire is just energy.

The case is similar to a lightbulb. The lightbulb has mass, there may even be a puff of smoke when the lightbulb burns out, but the light and heat emitted have no mass.

Answer 5

Yes it does. Smoke has weight so I think a flame could have weight. Take the weight of the gas that you are burning minus the weight of the smoke = the weight of the flame.

Answer 6

Weight? No But if it is intense enough it does cause pressure which can be measured.

Answer 7

flame has no weight
