Answer with Explanation:
The units used to express the densities of gases are different from those of solids and liquids because the particles in gas are widely separated from each other, unlike the particles in solid and liquid <u><em>which are almost the same</em></u>. The particles in solid are very close together. Considering it melts (if it's an ice), it will turn into a liquid and the change in volume is slightly greater only. However, if the liquid evaporates and transitions into a gas, <u>the volume becomes largely different from its solid and liquid state</u>. This is because the particles are much farther apart and free to move.

hi? you so cute.. hahahaha..... hakdog
The answer is A, I hope this helps you!
As temperatures increase, additional heat energy is applied to the constituent parts of a solid, which causes additional molecular motion. Molecules begin to push against one another and overall volume of a substance increases. When thermal energy is added to a substance, it’s temperature increases.
Remember the relationship
- P is indirectly proportional to V
So
The pairs are
- (2,4)
- (1,8)
- (4,2)
- (12,2/3)
- (2/3,12)
And so on
