Which would last longer actually depends on the temperature of the system (surrounding) they are exposed to. The temperature is more the ice will melt faster ut on the other end the water will last longer as it has the boiling point of 100 degree celcius so even if the surrounding temperature is more the water will last longer.
It depends what you are using it for.
If its cooling something Dry Ice
If you are eating the ice Its Water ice.
It depends on what you want to use it for. Water ice is good to cool down a drink so it is healthy to drink. Dry ice is used on commercial products to quickly cool down non edible products. Dry ice is solidified carbon dioxide, and we exhale the gas form of carbon dioxide. Water ice is used to cool down edibles, dry ice is used to cool down non edibles.
You take dry ice and water and mix it. the hotter the water the better the fog. the more reaction you get..
About the temperature of dry ice. It is the same as putting frozen water (ice) in a glass of water. The temperature of the ice and water will be about equal to the freezing point of water. Alcohol is used because it has a freezing point lower than H2O, if you put dry ice in water everything will freeze.
Because the pavement is more sturdeyer than the ice
The bubbles you see that come from dry ice are filed with carbon dioxide and water vapour the surface tension of the water causes the bubbles to happen and when you bow on them the presure of the wind breaks the surface tension releasing the CO2 and eater.
in water or anything which is denser than ice
No. The temperature of dry ice is far lower than that of ice water.
Dry ice is frozen carbon dioxide, totally different from ordinary ice, which is frozen water. Dry ice is much colder than water ice, thus evaporates quicker at room temperature. DO NOT TOUCH DRY ICE! It can hurt you badly.
Because dry ice evaporates faster in higher temperatures
dry ice
Rather than melts, dry ice evaporates. This process is called sublimation and happens at a slower rate than the melting of water ice.
Yes, ice is less dense than liquid water, regardless of its temperature. Dry ice will sink.
It generally forms water ice and carbon dioxide vapor.Dry ice is so much colder than the freezing point of water, if you drop dry ice into water the water will freeze. At the same time, water ice is so much above the freezing point of CO2 that the dry ice sublimates back into gaseous CO2.
Temperature causes changes in dry and water ice
You take dry ice and water and mix it. the hotter the water the better the fog. the more reaction you get..
Dry ice is solid carbon dioxide (CO2). It is called dry ice because it does not melt when it heats up, it goes directly from solid to gas. It is NOT the same as ordinary ice, which is of course, solid water. Dry ice is much colder than ordinary 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. Simply put, dry ice is colder than regular water ice and does not have the liquid residue that regular water ice leaves when subjected to high temperatures.

dry ice is for mixing with water to make fog
