I wondered if ice skating might not be a real world example of increasing pressure triggering the transition of solid to liquid. Ice skates are designed to focus body weight into a very small area. Ice is not slippery, but a thin layer of liquid water is downright dangerous.

Can you make a water freeze ray using this property. For example, have a container were inside it, the conditions are just that water will be liquid despite how low the temperature is, and then, (when or wile) the water is supper cooled a ultrasound speaker at the bottom will atomize the liquid into thick super cooled vapor. Perhaps the speaker would be consciously running at the bottom of the freeze ray ammunition generator; that way when the fog/water vapor condenses due to the freezing temperatures, the condensing water droplets will settle at the bottom briefly, make contact again with the speaker, and then re-atomize in a continuous cycle. Since liquid water is the most efficient way to contain water by volume, I think going form water to gas/vapor/fog through atomization should be the most efficient way. Am I wrong? Can it be done? Does atomization using ultrasound not work like that under those conditions? Please respond because I might have found a new project. Great video! Will the conditions inside be vacuous or pressurized? If there is a way to utilize these phase transition conditions in this way in a pressurized environment that would be great because the firing mechanism is easier. If it has to be vacuous its not the end of the world I am sure there is a way to get the vapor out.

Sir you have told that as pressure of triple point of water is same as that of mars as you say , then they all 3 phase will exist but the temperature is not same triple point temperature so 3 phase will not exist

Hi! I have a question about the CO2 at 1 atm. Below -78.5C it’s pure solid, exactly at -78.5C it’s solid and gas, and at 31 it’s gas only, right? Then why if I take a piece of dry ice and put it on my desk (let’s say room temp is 31C) it’s solid and gas again?

The same reason as to why a piece of ice from your freezer placed on your desk, doesn't immediately melt completely, instead it takes time to absorb enough heat from the air molecules to melt. (It takes time to sublimate the dry ice at room temperature)

Michel van Biezen Hi, thank you, it makes absolutely sense. I,m watching again the video and looking at the phase diagrams and I see that if I’m at the transition line liquid-gas, in order to reach the boiling point at higher pressures I need to add heat to the liquid. Now, if I go backwards, as I lower the pressure the temperature lowers too, does this happens automatically? How does heat is lost from the liquid as you decrease pressure to keep it boiling?
