To understand the kinetic molecular descriptions of solids, liquids, and gases.
The following table gives information about the behavior of molecules in solids, liquids, and gases.
| Solid | Liquid | Gas | |
| Density | high | high | low |
| Molecular movement (with respect to one another) | minimally | slow | fast |
| Compressibility and thermal expansion | fixed volume | fixed volume | variable volume |
| Do they expand to fill their container? | no | no | yes |
| Do they take the shape of their container? | no | yes | yes |
Part B
Consider equal volumes (say 1 L) of a given substance in the solid, liquid, and gas phases. Arrange them in order of decreasing mass based on the trend for the average substance. If the mass difference between samples is relatively small (10%or less), rank the items as equivalent.
Rank from greatest to least mass. To rank items as equivalent, overlap them.
1L of substance in the solid phase, 1L of substance in the liquid phase, 1L of substance in the gas phase
Greatest Mass Least Mass
Part C
Match each description to the appropriate phase of matter.
A substance with a fixed volume and fixed shape
A substance with no fixed volume or shape
A substance with a fixed volume and no fixed shape
Solid Liquid Gas
