Will a candle stay lit in a vacuum?

D. A candle can burn in zero gravity, but the flame is quite a bit different. Fire behaves differently in space and microgravity than on Earth.

Why does a candle stop burning when placed in vacuum?

It depends on how quickly you vacuum. If you drop the pressure slowly the candle will just slowly dim and eventually stop burning because there is not enough oxygen to sustain the burn. If you vacuum out the air quickly the candle will die quickly.

What happens if you close a lit candle?

The lid closes off the candle to any new air, so the flame uses up all the oxygen in its enclosed environment and dies. This method causes very little smoke or smoldering, and any smoke that is emitted when the flame goes out is contained under the lid and not stinking up the room.

Why does fire create a vacuum?

Air would be pushed out until the fire reached its critical point at which time the density of air in the room would stabilize. From that point, the room would begin to cool down which would produce lower density, creating a partial vacuum.

Why does cold water boil in a vacuum?

Water actually boils at a lower temperature if the pressure around it is lowered. In a vacuum chamber, the pressure can be extremely low. So low, in fact, that water can actually boil at room temperature. So, if you put some water in a high-vacuum chamber you will see it boil.

Do candles consume oxygen?

This shows that the candle flame requires an oxygen level of greater than 18.8\% oxygen to remain alight.

Is it safe to put out candle with lid?

Assuming the lid has no flammable material on it, such as a rubber gasket, it’s technically not a problem to snuff out the flame by using the lid. However, smoke will be trapped inside, which could affect the scent.

How do you unseal a candle?

Fill a sink with very hot water and submerge the candle jar. Allow the jar to soak for 5 minutes, then attempt to remove the lid. If it still doesn’t budge, return the candle jar to the hot water for another 5 minutes.

How do you explain a vacuum to a child?

A vacuum is a space with nothing in it—not even air. There is no such thing as a total vacuum because it is impossible to remove all the air or particles from a space. But partial vacuums are common. A partial vacuum is a space with almost no air or particles inside.

How does vacuum occur?

In general, a vacuum is created by starting with air at atmospheric pressure within a chamber of some sort. As molecules are removed, there are fewer other molecules for a given molecule to collide with the distance becomes longer and longer as the pressure is reduced.
