Yes, dry ice does melt in water. Dry ice also sinks in water. Dry ice has a density of 1.2 grams-per-centimeter cubed which is greater than water's density of 1 gram-per-centimeter cubed.
Check link below for more information on dry ice and dry ice makers.
EDIT:
Dry ice does not melt, it sublimates (skips being a liquid and goes straight from solid to gas).
Yes you can, you just need to drop the dry ice into the water and voila, you've got frozen water
Dry ice changes directly from a solid to a gas through sublimation. The change in water ice is due to melting, where heat energy is absorbed to break the hydrogen bonds holding the water molecules together, resulting in a phase change from solid to liquid.
Dry ice is called so because it consists of solid carbon dioxide, rather than water ice. When dry ice melts, it sublimates directly into carbon dioxide gas, without leaving a liquid residue, which is why it is termed as "dry" ice.
When the ice is put in warm water it dissolves.
No, it is not safe to put dry ice in a pool. Dry ice can lower the temperature of the water too quickly, potentially causing harm to swimmers and damaging the pool equipment.
Dry ice
An ice cube will dissolve in water because the water is warmer than the ice.
Ice melts. Dissolve is used for things that degrades when added to water.
heat
dry ice is for mixing with water to make fog
No. The temperature of dry ice is far lower than that of ice water.
cold water makes dry ice closer to its freezing point. so hot water makes dry ice sublimate more
No. Dry ice is carbon dioxide in the solid state. Regular ice is solid water.
Dry ice is CO2 and water is H2O; all the chemical properties are different.
You will have some dry water sodium. Salty dry ice.
Both dry ice and ice have cold temperatures and are commonly used for freezing and cooling. Ice forms at 32°F while dry ice forms at minus 109.3°F. Water ice is created when water is exposed to very low temperatures while dry ice is frozen carbon dioxide. Their main difference however lies in the fact that regular water ice melts into liquid while dry ice sublimates directly from solid to gas. Dry is also more dense compared to regular water ice, thus dry ice sinks in water while regular water ice floats.
