Dry ice sinks in water because it's more dense than water. Dry ice isn't made of
frozen water, and isn't related to 'regular' ice in any way (except that they're
both cold). There's no reason to expect it to behave like regular ice does.
The countertop is smooth and the bottom of the ice is flat causing it to slide
It floats on a cushion of gas.
Dry ice is not an element. Dry ice is solid carbon dioxide, CO2, which is a compound.
No need to cool dry ice.
dry ice is frozen co2
Temperature causes changes in dry and water ice
dry ice is the solid form of co2
Dry Friction
A beaker of Dry Ice will have VERY cold, glass walls. The moisture in the surrounding air comes into contact with the cold surfaces, condenses and freezes on them. Thus, your ice formation on the beaker.
ice is slippery and dry ice is not because ice dosent dry out when the sun hits it and dry ice does!
The flat and the curved surfaces. In ice cream cone terms the ice cream and the cone are the two surfaces. Even if you eat the ice cream and the cone gets empty there are 2 surfaces, the inside and the outside curved surfaces.
a molecular solid...
sliding friction.
yes they can be use on both, although dry surfaces work much better.
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.
Yes, dry ice is opaque.
Dry ice is frozen carbon dioxide.
Do you sell dry ice
Simple. You keep ice in dry ice. But be careful not to eat dry ice!
