Why did the dry ice smoke falls to the floor and flow downwards?
Dry ice, carbon dioxide, is more dense than air.
Changing state from solid to gas?
Dry ice can change from solid to gas without liquid state. When this occurs it is called 'to sublime'
What is the chemical name of dry ice. why is it called dry ice. Is dry ice is same as the ordinary ice?
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.
