Question

CO_2 sublimes readily at 25°C. Which properties are usually associated with a compound that undergoes this kind of change?

Answer 1

Step-by-step explanation:

Sublimation is defined as a process in which solid state of a substance directly changes into vapor or gaseous state without undergoing liquid phase.

For example, naphthalene balls show sublimation at room temperature.

As this process does not cause any change in chemical composition of a substance. Hence, it is known as a physical process.

Similarly, when
`CO_(2)` sublimes readily at
`25^(o)C`. This shows change in physical state of carbon dioxide is taking place, i.e, from solid to gaseous phase.

Thus, we can conclude that when
`CO_(2)` sublimes readily at
`25^(o)C` then it means physical properties are usually associated with a compound that undergoes this kind of change.
