Does it show the answer choices ?
Answer:
They went from atoms to oxygen molecule.
Explanation:
I'm not sure if this is the answer your teacher is looking for, but in simple terms you had 2 oxygen atoms. Together they make an oxygen molecule, which is the stuff we breathe.
While ethanol being an alcohol does have a direct O−H connection. Hence, ethanol has intermolecular hydrogen bonds. Therefore, more stroger physical bonds have to be destroyed in ethanol, than in acetone. Hence, acetone evaporates faster than ethanol inspite of having higher surface tension.
<h3>What is Vapor pressure ?</h3>
The pressure that a vapour exerts on the condensed phases (solid or liquid) in a closed system when they are in thermodynamic equilibrium with one another is known as vapour pressure (or equilibrium vapour pressure).
- It is significant to remember that when a liquid boils, the pressure of its vapour equals the atmospheric pressure. For instance, the vapour pressure of water when it boils at sea level is 1 atmosphere because the surrounding pressure is also 1 atmosphere.
