How long will it take to warm the water at 20 degrees to 3000 degrees at 3800?
To calculate time, there must be heating power, heating methods, water quality and physical state. If a small drop of water is placed in a 2000C graphite crucible, the water instantly becomes vapour, and some of the water molecules are broken down into hydrogen and oxygen.
The temperature of the heater can not be reached 3800C unless heated by high-energy laser, high-energy electron beam, plasma, etc.. However, the heating area can reach the high temperature equipment can be achieved is very small, but also have the conditions of use, such as electron beam high vacuum environment (water can not reach the requirement of high vacuum), laser heated material can absorb light energy (water absorption), the velocity of gas plasma is very high, very fast cooling the total energy is very small.
You don't want it either, because the thermodynamic chart is the highest, that is, the superheated vapor data of the 1000C. In addition, in the absence of a catalyst, at 1800K and 1mmHg, the water vapor begins to decompose into H2, O2, H, O, OH. At 3500K, all the water vapor breaks down into H, O atoms.
