Dry ice is sold in a two forms... blocks and pellets. Now, the pellets come in a few different sizes. 1/8", 1/4", and 1/2".
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.
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.
Rather than melts, dry ice evaporates. This process is called sublimation and happens at a slower rate than the melting of water ice.
Yes, you can put dry ice in salt water. It will bubble furiously and cool down the salt water.
Dry ice doesn't melt. It sublimates at -78 0C, or -109 0F. Sublimation is a direct transition from a solid to a gas, skipping the liquid phase.
its a solid it goes from sold to gas
Yes, you can buy dry ice in Pak'n Save. Dry ice is a commonly available product that is sold in many supermarkets, including Pak'n Save. You will typically find it in the frozen goods section.
The cold ice is called dryice, you can go to the mart or some whereelse.
If you drop a chunk of dry ice into warm water it crates a fog and bubbling effect. You can also add dishsoap to get bubbles coming out of the container. *Never touch Dry ice with bare skin you thick glove or tongs. *Dry ice is sold in most supermarkets.
a molecular solid...
Simple. You keep ice in dry ice. But be careful not to eat dry ice!
Dry ice is frozen carbon dioxide.
Yes, dry ice is opaque.
Do you sell dry ice
Dry ice freezes and the wet ice and everything keeps cool and chilled but not frozen..obvousliy.
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.
I assume you mean the sound dry ice can make if a flat piece of dry ice is forced onto a warm, smooth, non-porous surface, such as a knife blade or counter top. This happens because the dry ice is undergoing a phase change straight from a sold to a gas; the gas is trapped between the dry ice and the surface you are pressing it against, and it causes a vibration as it escapes that you hear as a squeak or a scream (this is the way all sounds are made, just vibrations propagating through the air to your ears). You will notice that the sound goes away once the surface you are holding against the dry ice cools off and stops accelerating the conversion of CO2 from a solid to a gas.
