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: Niezgodnaphysics riddles »very easy 92% glacierglacier309solidified CO2solidified CO28421legendary alchemical substancelegendary alchemical substance224meringue dessertmeringue dessert149 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.orgAntarctic riddles »very hard 35% a cracking noisea cracking noise2254a fizza fizz1700a roara roar378a whispera whisper503 On which of the following lakes are icebreakers most extensively used?Lake Superior.

Why is it elevated?To avoid being buried in snow. All structures at the South Pole cause wind-blown snow to build up in the surrounding area (about four feet of snow per year). The station building has sloping lower portion of wall, which causes the snow to be scoured away.Created by: Debbie Foxtechnology riddles »very hard 39% for earthquake safetyfor earthquake safety201to reduce heat lossto reduce heat loss937to avoid heating the groundto avoid heating the ground519to avoid being buried in snowto avoid being buried in snow1081 Which water phase is the most dense?Liquid water.
