I'm assuming A, but it says modern, so..
n = 5
l = 0,1,2,3,4
ml = -4,-3,-2,-1,0,1,2,3,4,
ms = +1/2 and -1/2
Solid state of matter
- the atoms are tightly packed in orderly form, they slightly vibrate but are stuck in a fixed position. Solids cannot be compressed and they maintain their shape
The air escapes into the atmosphere.
An <em>emulsion</em> is a colloidal dispersion of one liquid in another liquid in which it does not dissolve.
<em>Ice cream</em> is essentially an emulsion of the fat in milk with a sugar solution trapped in a network of small ice crystals. Other chemicals are added to prevent the emulsion from separating, and air bubbles are mixed into the semisolid mixture.
<em>Up to 50 %</em> of the volume of ice cream can be air.
When the ice cream melts, the air bubbles are <em>no longer trapped</em>. They just escape into the atmosphere.
If you re-freeze the melted ice cream, its volume will be much less than the original.
