Dry ice sublimates fastest in iodine due to the interaction between the two substances. Iodine has a relatively low boiling point and can create a higher local vapor pressure, facilitating the transition of dry ice from solid to gas. Additionally, the presence of iodine can lower the sublimation point of dry ice, enhancing the sublimation process. This combination of factors leads to accelerated sublimation rates in the presence of iodine.
dry ice
Yes
cold water makes dry ice closer to its freezing point. so hot water makes dry ice sublimate more
Putting dry ice in water causes it to sublimate more quickly, releasing carbon dioxide gas at a faster rate. The water helps transfer heat to the dry ice, causing it to sublimate faster and therefore increasing the amount of gas produced.
When more dry ice is added to a container with existing dry ice, it will sublimate and create more carbon dioxide gas. This can cause an increase in pressure inside the container, potentially leading to a build-up of gas. It is important to handle dry ice with caution in a well-ventilated area to prevent any safety hazards.
Iodine crystals will sublimate to iodine gas without going through a perceivable liquid state.
Sublimation is the transition of a substance directly from the solid to the gas phase without passing through an intermediate liquid phase. Things that sublimate are ice, iodine, and carbon dioxide.
dry ice
No, but it will evaporate (or, more properly) sublimate.
Yes
it can sublimate faster in hot water

It's the same principle as if a liquid is evaporating, for example. It requires thermal energy to evaporate the liquid, or to sublimate a solid; therefore, this process will cool down (in this example) the dry ice, and the surrounding air.
Dry ice only melts when it is under pressure of 5.1 atmospheres.

To reduce dry ice loss, make sure to pack dry ice as close to each other as possible. Fill any empty space with new bubble packs, newspaper or Styrofoam peanuts since the space will cause the dry ice to sublimate faster.
Examples of sublimation include mothballs, where solid naphthalene sublimes directly into gas, and freeze-dried food, where ice crystals in frozen food sublimate without melting into water. Sublimation also occurs in the purification of some chemicals and in the creation of artificial snow.
