Solid carbon dioxide (CO2) is called dry ice. this is a harmful substance to the human skin it can damage the human skin for life
Dry ice doesn't melt, it changes from a solid state, to a gas state, that's why it's called DRY ICE, there is no known way that it melts.
Sublimation. Dry ice, which is solid carbon dioxide, changes directly into carbon dioxide gas without passing through a liquid phase.
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.
It is called dry ice because it goes directly between a solid and gas state at-78 degrees Celsius, skipping the liquid phase.
a molecular solid...
There is no ice escaping. Rather the dry ice is becoming a gas. It's called sublimation.
turn directly into gas....
Solid Carbon Dioxide is called dry ice because on sublimation, it directly changes to gas. It does not have an intermediate liquid state. Thus, when it is frozen, it does not melt. Therefore, as it does not change into liquid and is dry, it is called Dry ice.
Dry ice is called so because it consists of solid carbon dioxide, rather than water ice. When dry ice melts, it sublimates directly into carbon dioxide gas, without leaving a liquid residue, which is why it is termed as "dry" ice.

Carbon dioxide is given off with dry ice. Carbon dioxide in compressed form is in solid state and is called dry ice.

It is called "dry" because when heat is given, it sublimes (turns from a solid into a gas). This is different from actual ice that turns from a solid to a liquid. It is called "ice" because solid carbon dioxide (dry ice) is very cold, similar to ice.
sublimation e.g dry ice to gas (CO2)
Dry ice is solid carbon dioxide. The conversion from solid to gas which carbon dioxide undergoes is called sublimination. the process where dry ice is changed into carbon dioxide is called sublimation.
It is called dry ice because it goes directly between a solid and gas state at-78 degrees Celsius, skipping the liquid phase.
