Liquid diamonds cannot exist.

I thank you for this challenging debate.Diamond Definition I will start out by immediately rejecting Con's definition of a diamond. Indeed, I did not define what a diamond was, since this is such a universal fact. However, I am obligated to point out the definition according to Merriam-Webster is the following:diamond a very hard usually colorless stone that is a form of carbon and is used especially in jewelryWhat form or allotrope of carbon are they referring to? Well diamond of course. Here is more information on this particular allotrope of carbon: A diamond is a transparent crystal of tetrahedrally bonded carbon atoms in a covalent network lattice (sp3) that crystallizes into the diamond lattice which is a variation of the face centered cubicstructure. Diamonds have been adapted for many uses because of the material's exceptional physical characteristics. Most notable are its extreme hardness and thermal conductivity (900–2,320 W·m−1·K−1), as well as wide bandgap and high optical dispersion. Above1,700 °C (1,973 K / 3,583 °F) in vacuum or oxygen-free atmosphere, diamond converts to graphite; in air, transformation starts at ~700 °C. Diamond's ignition point is 720 – 800 °C in oxygen and 850 – 1,000 °C in air. Naturally occurring diamonds have a density ranging from 3.15–3.53 g/cm3, with pure diamond close to 3.52 g/cm3. The chemical bonds that hold the carbon atoms in diamonds together are weaker than those in graphite. In diamonds, the bonds form an inflexible three-dimensional lattice, whereas in graphite, the atoms are tightly bonded into sheets, which can slide easily over one another, making the overall structure weaker. In a diamond, each carbon atom is surrounded by neighboring four carbon atoms forming a tetrahedral shaped unit.Find more here: http://en.wikipedia.org...Impurities in Water and DiamondImpurities are associated with water and diamonds. When we describe what water is, we will classify it as H2O. When we discuss the properties of water, we will discuss autoionization and other related topics. Water isn't the hydronium or the hydroxide ions floating in it. It just so happens that wherever water is, we will find said ions. Diamonds contain impurities, but that isn't what diamond is. When we discuss diamond, we keep note that absolutely 100% pure diamonds don't exist. It's the carbon network solid we are discussing for melting diamonds.Carbon Phase DiagramLet me teach the audience here what a phase diagram is quickly since the way Con presented it was very misleading. The state that matter is in depends on both pressure and temperature. We can plot pressure on one axis and temperature on another. Each element and molecule contains its own phase diagram that usually has a solid, liquid, and gas state. Carbon is much more tricky though. Carbon has many different allotropes for solid. One that many people are familiar with would be graphite. These allotropes get divided into the solid region of carbon on the phase diagram. The phase diagram that Con showed was that of CARBON and not DIAMOND. Only when the pressure and temperature when plotted on that graph lie in the area of diamond, carbon is diamond. That statement is probably very confusing but absolutely vital for understanding. Once it leaves the diamond area and into the molten carbon (liquid), it is no longer diamond. You can melt diamond, but liquid diamond will not exist ever.The ResolutionCarefully note the resolution. It states that liquid diamond cannot exist. It doesn't say that diamond cannot melt. There is a huge difference between these two. Con has proved that diamond does indeed melt (which I totally agree with), but hasn't provided evidence that it can exist as a liquid. The phase diagram shows that carbon can exist as a liquid, not diamond.ConclusionThis was a very interesting debate. I can't wait to see your rebuttal to this. I want to ask you a few questions though. Why did you accept this debate? Were you simply testing my knowledge on this topic? Were you playing the devil's advocate? I really want to know. This was challenging for me, but I can't imagine your frustration trying to prove a fact wrong. I really appreciate this challenge though and thank you.Sources1. http://www.merriam-webster.com...2. http://en.wikipedia.org...
