RossHot ice, also known as sodium acetate, is commonly used in hand warmers or reusable heat packs. When crystallized, it generates heat as it solidifies, making it a convenient and portable heat source for various applications. Additionally, it can be used in certain chemical reactions or demonstrations in the laboratory.
Hot ice is crystallized sodium acetate trihydrate.
If normal sodium acetate dissolved in water crystallises it will generate heat(it's called an exothermic reaction), that's why it's called hot ice.
So hot ice isn't real ice: water/H2O in it's solid state.
It's crystallized sodium acetate dissolved in water
Molecular formulas:
Sodium Acetate: NaCH3COO
Sodium Acetate trihydrate: NaCH3COO . 3H2O

Do you use hot water to make an ice rink?
No, hot water should not be used to make an ice rink. Cold water freezes faster and results in a smoother ice surface. Hot water can also create weak spots in the ice, making it less safe for skating.
What are some uses for cold packs?
Salt added to ice makes the ice colder than 32 degrees Fahrenheit. Salt and Ice are also used separately as preservatives. Salt is used as a flavor enhancer. Ice is used to make drinks more palatable.
Would ice cubes melt in hot water first or will the ice cubes freeze the water first?
The ice cubes will melt in the hot water first. The heat energy from the hot water will transfer to the ice cubes, causing them to melt.
Why does dry ice melt faster in hot water than cold water?
Dry ice sublimes directly from a solid to a gas when exposed to warmer temperatures. In hot water, the increased temperature causes the dry ice to sublime more rapidly compared to in cold water. This results in faster melting or disappearance of the dry ice in hot water compared to cold water.
Is it hot or cold in the Antarctic ice?
Cold
