Answer: 385.4132857
Explanation:
Using the equation, PV=nRT, you can solve this problem.
P= 3.5 kPa V=? n= 0.55 moles of air T= 295K R= 8.314 (L kPa/mol K)
We use the constant rate of <u>8.314</u> because we are using kilopascals in this problem.
Using simple algebra we get-
V = (0.55 moles)(8.314 L kPa/mol k)(295 K) / 3.5 kPa
Using the calculator, we would get the answer of 385.4132857 L.
And whatever the significant figure is asked for, for example, 3 significant figures: the answer would be 385 liters.
I believe the change of state shown in the model is deposition.
Deposition is a process in which gases change phase and turns directly in solids without passing through the liquid phase. It is the opposite of sublimation.
One of the major difference between gases and solids is the distance between molecules; in gases the inter molecular spaces are large, while in solid they are very small, making solids be the most dense, with closely packed molecules. This is evident in the diagram, the phase changed from gases to solids.

Hopefully this helps :)
The answer is more protons than electrons.
