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.
What else can I help you with?
How does the temperature of water affect the sublimation of dry ice?
cold water makes dry ice closer to its freezing point. so hot water makes dry ice sublimate more
What makes Dry Ice melt?
Dry ice doesn't melt, it changes from a solid state, to a gas state, that's why it's called DRY ICE, there is no known way that it melts.
Is nitrogen dry ice?
No, dry ice is frozen carbon dioxide, or CO2.
What substance makes up dry ice?
Carbon dioxide .
Dry ice lemon juice and soda?
It makes erratic bubbles
How does dry ice in a ice cream cart disappear?
Dry Ice is made up of a chemical. When exposed to air it dissipates. The more the air gets to it the faster it disappears. To make you dry ice last longer, just keep your container closed and make sure it is air tight. The Ice Cream Man
What makes dry ice get smaller and smaller?
sublimation..dry ice is frozen carbon dioxide.. it skips a liquid phase and changes directly from a solid to a gas when its temperature rises
Does dry ice cool faster?
Yes, dry ice can cool more rapidly than regular ice because it sublimates directly from a solid to a gas, absorbing more heat in the process. This rapid cooling effect makes dry ice useful in applications where a quick temperature drop is needed.
What is solid CO2 called?
a molecular solid...
Why does it take longer for cars to stop on pavement covered in ice then pavement that is dry?
WHY!It is because the ice makes the friction between the tires and the pavementgreater.
Is dry ice safe to put in drinks?
Yes. Dry ice is safe to put in drinks. It's only carbon dioxide (the same thing that makes soda fizzy) in it's frozen form. However, it is not safe to ingest. Ingestion of dry ice would result in a hospital visit. Also, putting in too much dry ice will cause the drink to freeze and be undrinkable.
What makes liquid bubble?
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.
