Sublimation.

Sublimation of an element or substance is a conversion between the solid and the gas phases with no intermediate liquid stage

There is a process called sublimation, I think this is the transformation of a matter from gaseous state to solid without going through the liquid state (remember this? gas->liquid->solid). So if they say that flame is a combustion of "gases", maybe it can be frozen by the process of sublimation.

No, a flame is very hot and has a specific temperature for every fuel, for freeze something you need to lower the temperature, if a flame is cooled it can't exist already. To freeze a flame is a contradiction.

A flame cannot be physically frozen because by it's very definition it is the combustion of gas.
In my mind there are only two ways to 'freeze a flame'
1. Take a picture of it
2. In theory, if the flame was near a gravity well (eg an event horizon of a black hole) it would appear to be frozen if observed by someone a great distance away and unaffected by the time dilation effects.
What a strange question to ask....

I don't think that a flame can be frozen.
What you see in a fire is a plasma--charged excited states of gases that are relaxing and emitting energy based on the magnitude of the relaxation.
I don't think that you can "freeze" a plasma in this excited state by lowering the temperature...you would have to continue to input energy (from the combustion) to provide the energy of excitation as the gases will relax to lower energy states spontaneously.
If you did "freeze" the plasma in the excited state, it would be invisible because if it isn't relaxing, it isn't giving off energy any more and then what is the point of freezing the fire? (I guess you could save the energy for later maybe...that would be neat.)

No. A flame is the interaction of gas burning... if you get the temperature down enough to freeze the gas the combustion would not be able to take place.

U cud if u knew what it is: vapour to solid sans intermediate liquid phase is called sublimation.

No.
To Have a flame you must have heat, fuel and oxygen. By freezing something you are removing the heat. Therefore it is impossible to have a "frozen flame"

flame is burning gas giving off light and heat
gas can be frozen but light and heat cannot
freezing the gas component would alter its shape and not look like a flame

It might be possible if you had the flame in a container of sorts, and flash-froze it to 0 kelvin, it would have to be frozen to ABSOLUTE ZERO IN AN INSTANT, way less than a nano-second. and it is impossible to get to 0 kelvin, nd to flash freeze, so NO

No because a flame is just a visual representation of heat. and you cant freeze heat because all it will do is get cold..so the flame would go out.

a flame is made of gaz or plasma (depending on the flame), something frozen is solid.
It's a terminology contradiction.
plasma, gaz, liquid and solid are the 4 possible states of matter, they are exclusive : you cannot be in one state AND another simultaneously. Especially plasma and solid which are opposites in terms of temperature and pression...
