Another behavior of a gas is that the volume changes directly with [...]. | Another behavior of a gas is that the volume changes directly with temperature. |
As you change the amount of gas in a fixed volume, you change the [...]. | As you change the amount of gas in a fixed volume, you change the pressure. |
[...] molecules can move from one side of a room to the other. | Gas molecules can move from one side of a room to the other. |
a net movement of the molecules from an area of higher concentration (the onion) to an area of lower concentration (the opposite side of the room) is called [...]. | a net movement of the molecules from an area of higher concentration (the onion) to an area of lower concentration (the opposite side of the room) is called diffusion. |
