Can unpressurized water be chilled to below 32°F (0°C), and not freeze?
That’s how you can get the cream below the temperature of ice by adding salt to the ice. By forcing the ice to melt it will pull the heat out of the cream to a much colder temperature than it was originally. Bingo. Ice cream in the summer
It takes 1 calorie per gram of water to convert ice to water or water to ice at the same temperature.
Great question. Super cooled water droplets impact airplanes and the energy of impact will convert the water to ice. It then sticks on the airplane and can cause loss of lift. We have heaters on the wings to melt it.
Depends on the contents of the water.
🤷🏻♂️ no clue 😊 outta my zone here.
Alternatively use very clean water in a smooth walked vessel, the ice won't have any nucleation points
you only have so many degrees of freedom. once you set P and T, and two phases (vapor and (L or S), you’ve fully defined the system.
Supercooling. Very pure water, clean, smooth container, and a whole lotta cold. By not providing any nucleation points for crystals to seed on, water can get as cold as -47°C without crystallizing. At -47°C, water has to crystallize.
Can you come up with an easier way?
You get the points though!
The answer is "yes." But how?
