It is immersed in an oxydizing, low density fluid medium, with decreasing density with increasing temperature, and a gravitational field to drive the flows based on density.

Does a burning candle maintain homeostasis?
yes, because if the external temperature changes to a cooler temperature, the lit candle flame gets smaller.
Why does candle wax disappear?
When the candle flame is burning, the flame heats the wax which melts it, the wick pulls in the liquid wax into the flame as fuel (this is why the wick doesn't just burn away). Think of a napkin soaking up water. The wax then burns in the flame and "disappears".
When a candle is put under a tumbler why its flame goes after some times?
When a candle is put under a tumbler , the flame goes after somtimes . This is all because all the oxygen present in the tumbler has been used for burning.
Why does a candle extinguish itself after being covered with a glass?
The burning flame on a candle needs three things to continue burning: 1) fuel, which it gets from the wick 2) heat, which comes from lighting the candle 3) oxygen Without any one or more of these three things, the candle will no longer continue to burn. In the case where a candle is covered with a glass, the candle quickly uses up the oxygen inside the glass. once all of the oxygen is gone, the flame will burn out.
What happens to a candle if there is no oxygen?
The candle will cease to burn because oxygen is needed for burning. This is why one of the ways to extinguish a flame is to remove its source of oxygen, as described in the fire triangle.
What happens to a burning candle if it has no oxygen?
If a candle has no oxygen, its flame goes out.
Which part of the candle melts when the candle is burning?
Normally the part closest to the flame (the wax).
It takes an initial spark or flame to light a candle what could be true regarding the burning of a candle?
The burning of a candle is spontaneous because it does not require continual input of energy.
What is the difference between a goldfish and the flame of a burning candle?
the goldfish is a living thing
Why does the flame of a candle die when you cut off air supply?
Oxygen is needed for burning. If there is no oxygen flame dies.
Whats actually burning on a candle?
the flame of a candle is a reaction of oxygen with carbon to form carbon(iv)oxide and vapour
How do you use the word flame in a sentence?
The most effective way to extinguish the flame of a candle is to use a candle snuffer.People returned to churches all over the land and kindled flames of revival that are still burning todayThe candle's flame was flickering in the soft breeze
Is a burning candle exothermic reaction?
Yes, a burning candle is an example of an exothermic reaction. When the candle wax reacts with the oxygen in the air, it produces heat and light energy as byproducts. This release of heat is what makes the candle flame feel warm to the touch.
5 example of qualitative and quantitative observations before burning a candle.?
qualitative - smells of smoke, hot air from flame, flame is orange and blue at the bottom, flame moves around, [unscented candle - no smell], wick is burning and turning black. quantitative - sorry i don't have the answer. I'm looking for it myself :(
Does a burning candle maintain homeostasis?
yes, because if the external temperature changes to a cooler temperature, the lit candle flame gets smaller.
How does a candle burn in the air?
A candle is able to burn in the air due to the presence of oxygen. The wick of the candle (usually made up of braided cotton) "draws" the wax up to the flame, providing the flame with combustible material to continue burning.
Why does candle wax disappear?
When the candle flame is burning, the flame heats the wax which melts it, the wick pulls in the liquid wax into the flame as fuel (this is why the wick doesn't just burn away). Think of a napkin soaking up water. The wax then burns in the flame and "disappears".
