1) What is dry ice?
Dry ice is carbon dioxide in its solid state. It is widely utilized since it has no liquid state and sublimates immediately from the solid to the gaseous state. It's usually utilized as a cooling agent, but it's also employed in theatre fog machines for dramatic effects.
Why is it bad to pick it up with bare hands?
Dry ice sublimates into carbon dioxide gas, which is a natural component of air, when heated. Touching dry ice has the disadvantage of being extremely cold (-109.3 F or -78.5 C), therefore the heat from your hand (or other body part) is absorbed by the dry ice.
2) What does temperature have to do with phase change?
The terms "change of phase" and "change of state" are interchangeable. A change in phase is always accompanied by a change in heat. The temperature, on the other hand, does not alter. When we heat a solid, the energy we supply is used to increase the kinetic energy of its molecules, resulting in an increase in temperature.
3) Are there other phases beside solid, liquid and gas?
Solids, liquids, gases, and plasma are the four natural states of matter. The man-made state is the fifth state. Condensates of Bose-Einstein
4) What phases occur on other planets?
A planetary phase is the region of a planet that reflects sunlight as seen from a certain vantage point, as well as the time period during which it happens. As seen from Earth, other planets in the solar system appear to go through phases as well. When compared to the other planets, Venus and Mercury have the most visible phases. This is due to their orbital distances from Earth.
