I NEED HELP PLEASE, THANKS! :) Explain the process of sublimation. Name one substance that sublimes at room temperature and pressure.

Here's what I get  

Explanation:

Sublimation is the conversion of a solid directly to a gas, without passing through the liquid state.

It occurs when the molecules of a solid have absorbed enough heat (kinetic energy) for some molecules to overcome the attractive forces of their neighbours and escape directly into the vapor phase.

One substance that sublimes at room temperature and pressure is CO₂ (dry ice).

thats a little if u want the answer just look it up on google thats what i do haha : )

in the analysis of systems that involve fluid flow, we frequently encounter the combination of properties u and pv.
