Can dry ice be refrozen to reuse?

Not in a normal freezer.. It freezes at around -70 celcius


Will dry ice melt on contact with salt?

No, dry ice will not melt on contact with salt. In the first place, dry ice does not melt. It does not have a liquid phase under normal atmospheric pressure. It transforms from solid to gas, which is called sublimation. Dry ice sublimes, rather than melts. Secondly, salt has no effect on the sublimation of dry ice. Salt has an effect on frozen water, but it does not have an effect on frozen carbon dioxide. Salt is soluble in water, it is not soluble in carbon dioxide.


How fast does dry ice melt?

Dry ice sublimates rather than melts. It turns directly from a solid to a gas at -78.5°C (-109.3°F) at normal atmospheric pressure. The rate of sublimation can vary depending on factors like temperature, surface area, and environmental conditions.


Does ivory soap melt?

Yes, Ivory soap will melt if exposed to high temperatures because it has a high glycerin content that causes it to soften and eventually melt. It is recommended to store Ivory soap in a cool, dry place to prevent melting.


Why is solid carbon dioxide is called dry ice?

That's precisely what it's made of. "Regular" ice is made of solid water, also known as H2O. Dry ice is made of solid CO2. If you meant to ask that question backwards, solid CO2 is called dry ice because CO2 in its standard state at room temperature is a gas, unlike water, which is a liquid, therefore "dry ice" evaporates and leaves no liquid.
