How do solids, liquids, and gases differ?

a. in solid matter, atoms or molecules pack dose to each other in fixed locations; in gases, atoms or molecules pack about as closely as they do in solid matter, but they are free to move; in liquid matter, atoms or molecules have a lot of space between them and are free to move

b. in solid matter, atoms or molecu es pack dose to each other but, they are free to move; in liquid matter, atoms or molecules pack about as closely as they do in solid matter, they are also free to move; in gaseous matter, atoms or molecules have a lot of space between them and are free to move relative to one another

c. a solid has a fixed volume and rigid shape; gases assume the shape of their container; liquids always assume the shape and volume of their container

d. a solid has a fixed volume and rigid shape; liquids assume the shape of their container; gases always assume the shape and volume of their container

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
