Ice questions This is a list of recently added questions about ice. What is dry ice?Solidified CO2. Dry ice is used in refrigeration. It has an interesting property: it maintains a constant temperature of -78.5C in a warmer environment. This is because dry ice does not melt and sublimes directly into the gaseous form.Created by: Niezgodnavery easy 93% glacierglacier465solidified CO2solidified CO213497legendary alchemical substancelegendary alchemical substance305meringue dessertmeringue dessert205physics riddles » What sound can be heard when approaching an iceberg?A fizz. When a piece of iceberg ice melts, it makes a fizzing sound called "Bergie Seltzer". This sound is made when the water-ice interface reaches compressed air bubbles trapped in the ice. As this happens, each bubble bursts, making a 'popping' sound. The bubbles contain air trapped in snow layers very early in the history of the ice, that eventually got buried to a given depth (up to several kilometers) and pressurized as it transformed into firn then to glacial ice.Created by: globalquiz.orgvery hard 33% a cracking noisea cracking noise3871a fizza fizz2720a roara roar605a whispera whisper826Antarctic riddles » On which of the following lakes are icebreakers most extensively used?Lake Superior.
