At normal atmospheric pressure, carbon dioxide goes directly from the solid phase to the gas phase without ever being a liquid in between. The technical term for this is "sublimation." It is possible to have liquid carbon dioxide at higher pressures, so strictly speaking it's not true to say that solid carbon dioxide can never melt ... it just doesn't happen at normal pressures.

Explain why solid carbon dioxide is known as dry ice?
Solid carbon dioxide is known as "dry ice" because carbon dioxide as itself cannot exist in liquid form. Therefore, the ice is "dry," which is why it's called "dry ice." It looks like ice and it keeps things cold but it isn't wet.
What common substance turns from solid to gas?
Carbon dioxide (CO2) turns directly from a solid to a gas, without any liquid phase, this is why it is often called dry ice when it is solid because it doesn't get wet.
How can gaseous carbon dioxide be converted into dry ice?
Carbon dioxide turns into what is known as "dry ice" which is fact solid carbon dioxide. It changes directly from a solid to a gas at about -56°C under normal atmospheric conditions without going through a wet liquid stage. This process is known as sublimation.
Is dry ice wet?
Dry ice is frozen Carbon Dioxide. This solid "sublimates"; it turns into a gas without being a liquid at all. So no. You can't get wet dry ice.
If you melt dry ice can you take a bath without getting wet?
Dry Ice is frozen carbon dioxide. Carbon dioxide (at atmospheric pressure) changes straight from a gas to a solid when cooled, and straight from solid to gas when warmed. If you filled a bath with dry ice and let it "melt" you would get a bath full of carbon dioxide gas. If you lay in it there is a potential for suffocation as the gas is heavier than air and will have displaced the air from the bath.
What are the similiarities between carbon dioxide and hydrogen?
Carbon dioxide and hydrogen are both non-metallic gases at room temperature. They are both involved in various industrial processes, such as production of chemicals and energy generation. Additionally, they both play important roles in the Earth's atmosphere, affecting climate and weather patterns.
Can you use wet and dry ice together?
Yes, wet and dry ice can be used together. Dry ice is solid carbon dioxide while wet ice is frozen water. When used together, dry ice can help keep wet ice colder for longer periods of time, making it useful for creating a long-lasting cooling effect.
What is the name of the change when a substance goes directly from a solid to a liquid?
The change is called "sublimation." Sublimation occurs when a substance transitions directly from the solid phase to the gas phase without passing through the liquid phase. Examples include dry ice (solid carbon dioxide) turning into carbon dioxide gas.
Why dry ice is named so?
Carbon dioxide has no liquid form. The solid sublimates to gaseous form directly. Because it has no liquid form it can't be wet to the touch, like ice is, yet it looks like ice. Dry ice.
Is yeast solid liquid or gas?
Yeast is a type of fungus and is typically found in a solid form, often as dry granules or in a wet paste. When activated in a liquid, such as dough, yeast ferments sugars and produces carbon dioxide gas, which causes dough to rise. So while yeast itself is solid, its activity can produce gas as a byproduct.
Why dry ice does not wet the surface on which it is kept?
The reason that dry ice does not wet the surface on which it is stored is because dry ice is not made of water, but instead it is made with Carbon Dioxide. Because of the state of matter CO2 is at room temperature, it goes directly from a solid to a gas in a process called sublimation. Because of this, it never passes through the intermediate liquid state, thus not leaving anything on the surface on which it is set.
Why is solid carbon dioxide known as dry ice?
Because it is very cold, it is white and frosted looking, when you touch it your hands don't get wet and it does not melt it just turns into co2 gas.Because when the "ice" melts there is no water remaining...
