In a hypothetical situation where liquid water can flash freeze in its entirety, what would happen to the energy in it? Is it enough to feel, cook or explode something inside or around the ice?
Assuming a 10 cubic foot cube of water or 283 liters, at 20 degrees C. It freezes instantly, 1 second or less. I found a number that it would take removing 417 kj to bring 1 liter to 0 C and crystallize it. At 283 liters that's 118 Megajoules. 32 kWh, 66 lbs/29 kg of TNT equivalent. 118 Mega Watts released as heat in a second.
- Are my numbers above correct?
- Would this energy be released like a simple heat wave, or an explosive similar to tnt? Convection?
- I am assuming that even if just heat, anyone feet away or worse in the middle would suffer significant injuries, right?
- Can water freeze this quickly?
