Question

What is called dry ice? And why it is?

Answer 1

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.

Answer 2

solid CO2 is known as dry ice because under high pressure CO2 changes into solid which has no water water particle in it but it looks like ice and is much more colder than ice
