Ice expands as it warms. At 4 degrees C water achieves it's maximum density.
Warm ice is less dense than cold ice.
Any amount of liquid water would mean that the ice has gotten as warm as it can get and that it is in equilibrium with the liquid water. The ice, being crystalline, has a discreet melting point so it is either water or it is warm ice.
If the ice is wet, it is less dense than ice that is cold enough that the water in contact with it freezes. That doesn't mean that warm ice must be wet ice. If the water is removed, the dry ice will be the same density as the wet ice of the same temperature.
Having said that, it is possible that you want to contrast the density of frozen carbon dioxide to water ice.
* Water ice has a density of 0.92 g/ml * Dry ice (CO2) has a density range from 1.4 to 1.6 g/ml

What will make the dry ice melt?
Dry Ice doesn't have a liquid state under normal conditions; it transforms straight from solid to gas. In order to melt dry ice, it would need to be at a higher outside pressure than our atmosphere provides -- at least five times the air pressure at sea level. Then it would melt, but at normal Earth temperatures, would almost immediately boil.
What are some good titles for science fair experiments with dry ice?
Use modeling clay to shape a volcano, then fill it with water and when you are giving your presentation, drop dry ice in it, it will begin to make fog.
Why does dry ice evaporate faster than a regular ice cube?
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.
What is it called When a solid skips the liquid state and goes straight to a gas.?
It's called "sublimation". Dry ice does that at normal atmospheric pressure.
Is dry ice a solid liquid or a gas?
Dry ice is the solid form (state of matter) of carbon dioxide (CO2).Under normal circumstances, it will change state from a solid directly to a gas. It does this without melting (changing state to a liquid). We call the direct transformation of a solid to a gas sublimation, and dry ice is said to sublime when going directly from its solid state to a gas.
Is the ice found on Mars dry ice or normal ice?
It is a mixture of the two.
Can dry ice float a hot air balloon?
No. Dry ice is frozen carbon dioxide, which is heavier than air, so wont float a balloon.
Why doesn't the balloon float when filled with evaporated dry ice?
Dry ice is frozen carbon dioxide. Sublimated carbon dioxide is heavier than room air and will not float.
Can you mix dry ice with nomal ice?
It is not recommended to mix dry ice with normal ice because dry ice is extremely cold (-78.5°C or -109.3°F) and can cause the water from the normal ice to freeze quickly. This could create a hazardous situation and increase the risk of frostbite or injury. It's best to use dry ice separately and handle it with care.
Can dry ice be refrozen to reuse?
Not in a normal freezer.. It freezes at around -70 celcius
What to do with a swelling knee?
To get it back to normal put dry ice on it for ten minutes.
What is the normal temp of dry ice in deg c?
im not entirely sure, but round about -78 deg c
Why is dry ice why is it called so?
Dry ice is the solid form of carbon dioxide, instead of water. The reason why it's called dry ice is under normal circumstances, heating dry ice will turn it directly into a gas, skipping a liquid form. The exception in all cases is under high pressure will melting dry ice turn into a liquid.
How will dry ice form a dry ice bubble?
Well, this was answered by a 10 year old kid. It happens when a normal soap bubble meets co2 filling the bubble.
How will knowing that ice is heavier than water help you in your life?
ice is not heavier than water
Why does a cloud of dry ice flow downwards?
It flows downwards because it is cold and cold air sinkse. The most important reason why it flows downwards is that dry ice is made of CO2 / carbon dioxide which = 1.5 times heavier than the air that we inhale.
How do you classify dry ice?
Dry ice is the solid form of carbon dioxide. It would be classified as a molecular solid.
