Which of the following statements is true regarding the particle structure of liquids? Particles of a liquid are -

• very close together, so the liquid cannot easily change its shape

• fast-moving, so they fill the volume of their container

• relatively close together, so they cannot be easily compressed

• very far apart, so they have plenty of room to move around

Which of the following statements best describes gases? Gases -

• cannot easily change their volume by compression

• maintain a constant shape, regardless of the container

• can change shape and volume depending on the container

• have a fixed size and shape, regardless of the container

Which type of substances have a definite shape and fixed volume?

• Solids only

• Liquids and solids

• Gases only

• Liquids and gases

Liquids are not easily compressible. Which characteristic of the structure of liquids makes this true? In a liquid particles –

• are too close together to move any closer

• have freedom and space to move

• take the shape of their container

• always fill the volume of their container

A table showing data on four different substances is provided. Each substance was placed in two containers. Container #1 has a cube shape, and Container #2 has a spherical shape.

Which of the four substances was in the gaseous state?

• Substance A

• Substance B

• Substance C

• Substance D

Which of the following is true regarding the particle nature of a solid? Particles in a solid –

• move very little, so it cannot easily change its shape

• are relatively far apart, so it is highly compressible

• are in continual motion, and can slide past each other

• are very far apart, so it can easily change its shape
