Fun fact: the blobs of flames appear so viscous because they are actually very viscous. For gasses, as opposed to liquids, viscosity increases with temperature. In the old days, when there was no digital simulation available, modeling of combustion chambers was done using honey in water.

That sounds very interesting. I'd love to have a look at that, can you point me in the right direction? A quick google hasn't helped much. I'm sure the honey/water would be a decent model for combustion products/air and the viscosity does increase with temperature, but I'm assuming the flame in a (rocket?) combustion chamber isn't nearly as viscous as that. Right? I'd love to check that out if it's the case.

@@ThreeTwentysix I've learned this bit from an old professor who was at retirement age already thirty years ago. The course was, loosely translated, "modeling for thermotechnical studies" whereas "modeling" was meant as actually building physical models of the reality. The course was fully centered on dimensionless numbers, so that you only need to match Prandtl and Reynolds (and a plethora of other) numbers, rather than single material properties. I've tried too to google it to get some decent source, but this I think is a topic that still has to be scanned out from some dusty engineering library collection 😊

@@misiumHeat is transfer of energy between systems. Added heat adds to total energy of the system, therefore kinetic energy of particles,and therefore their velocity increases. Simplifying physics ,their velocity needs to increase as energy added to the system will be of the kinetic type, as they are in motion and cannot,in this situation, accept this energy as potential or energy that would otherwise, for example, excite electrons (such as it happens in cholorphyll molecules after accepting energy of a photon). Molecular composition of fire itself is highly dependent on the fuel type. If we know the composition of the fuel and the atmosphere in which the combustion happens, we can easily figure it out.

Incredible. When I was at senior/secondary school I was into my first year and we started to learn the basics of chemistry. I remember the teacher saying matter is in one of three states; gas, solid or liquid. I remember thinking about what he said and it got me wondering what fire was. This was around 1984. I remember stopping my chemistry teacher in the hallways and asking him, what is fire if matter can be in one of three states. I was met with a very puzzled face and was told that he'd never been asked that in all his years of teaching and would have to get back to me. He did with one very simple answer which I'll never forget... It's a visual release of energy. Loved your video, for some reason this ended up in my feed and if I was still into chemistry I would have subscribed instantly as you've explained everything so well so thank-you for that.

You could point to the solid wick, the liquid melted wax, the oxygen gas in the air, etc, and point out their state of matter in the process of burning, but fire is the process itself. Fire does not have a state of matter because it is simply the visual component of the chemical release of energy in a fuel during an oxidative process.

I'd say technically speaking what we CALL "fire" doesn’t really have a state of matter because it is not a single thing. It is a complex series of reactions between many components which are in shifting states of matter during that process. The question of states is overly broad, like asking "what color is paint" or "which city do people live in". "It's a visual release of energy." is a partial description of what we call fire but does nothing to answer the question of state. The question needs to zoom in a lot more to get any answer.

You're an amazing explainer. I found your channel a few days ago. I have a good tip for self learners. You're never to old to learn something. I am a computer scientist and I didn't really had the opportunity to dive deep into the field of chemistry. Channels like these will teach you a lot. The amazing thing is that you are able to learn practically everything if you devide the task into many smaller easy to handle tasks. This is the essence of what I call the algorithmic thinking of a computer scientist. If you make small enough planned steps, you will be able to climb the hill without exhaustion. Back in my younger days I had issues learning stuff because I wanted to have the whole cake. The hard truth I didn't want to be true was that in order to learn something you have to start with the basics. That means also that you sometimes have to go back to stuff like math or physics or basically any field that is relevant for your goal. This is the hard part, because it takes a lot of will to overcome this phase. But ONCE you crossed that line you will find yourself equipped with a beatiful and often powerful perspective of this world. You will have new skills you've never dreamed of and understand things more clear. I wish you good luck on your journey. You have it in you!

Nice video, In part valid for the methane-air or for a volatile flamable liquid; but probably this is way too oversimplified for the candle example ... what can't be as simple as a simple melting (leading to convection of the fluid and loss of viscosity to afterwards be absorbed by capilary into the wick; ascending to the top of the wick; then vapourize to mix with air and generate chemical and radiation heat (combustion))... In all that sequence, no mention of cracking (generation by heat of tiny molecules (sometimes gaseous, more volatile, more flamable), tiny atoms (more reactive with oxygen from the air); more unsaturated carbon squelton by dehydrogenation, dehydration or crackage); this process should happen way before volatilisation of high molecular weight molecules might happen. The reaction of methane forming sooth seems to me way too easy; Following the video, it seems like heating a little methane and air with sudden subsequent flash cooling will provide dihydrogen, water, paraffin wax (or graphite and maybe diamond in a sooth form). Sooth is not formed industrialy (or in the lab) with methane, methanol or ethanol; all those burn with a blue flame and leave no (or very little) combustion residue; the molecules of choice for carbon sooth are usually more of the type long alcanes (paraffin) or aromatic hydrocarbons; those are used with a lack of oxygen in a hot zone and contact of the exhaust reducing gases onto a cold condesation surface (inert metallic) to condense the sooth as "black of fumes".

I remember my year 7 science teacher asked us what fire actually is, I now do A Level chemistry and up till now I still didn't know.

This question was also explained by Richard Feynman, the jiggling guy. But not in such detail. You have a knack for teaching too. You talked about soot but what about ash...?

Ash is the metal oxides left behind from the wood.

At 16:45 the vid says that water is not going to give you energy. That's true, but the real significance of water is the cooling by evaporation that happens when you heat wood that contains large amounts of water.

Dr Robertson, what do you think of nuclear energy? As scientists, should we support electricity production via nuclear fission?

Cool video. It's another day, can I learn how the air can burn if it's hot enough?

How about a video about foaming liquids? I think this could be very interesting and there is not that much explanation of this seeming simple phenomena. Like foaming water when cooking pasta
