b. collide into each other
c. move slow
d. high kinetic energy
e. moving orderly

1. gases take both the volume and the shape of their container.

a. true
b. false

1. which of the following is/are physical properties of gases?

a. pressure
b. volume
c. number of particles
d. all of the above

1. which state of matter takes on the shape, but not the volume, of its container?

a. gas
b. solid
c. liquid
d. plasma

1. a has a fixed volume but takes the shape of its container.

a. liquid
b. solid
c. gas
d. plasma

Explanation:

• Question 6: Gas particles move randomly (a), collide with each other (b), and have high kinetic energy (d). They do not move slowly (c) or orderly (e).
• Question 7: Gases take the volume and shape of their container, so the statement is TRUE (a).
• Question 8: Pressure, volume, and number of particles are all physical properties of gases, so the answer is All of the above (d).
• Question 9: Liquids take the shape of their container but have a fixed volume, so the answer is liquid (c).
• Question 10: Liquids have a fixed volume but take the shape of their container, so the answer is liquid (a).

Answer:

1. A. moving randomly, B. collide into each other, D. high kinetic energy
2. A. TRUE
3. D. All of the above
4. C. liquid
5. A. liquid
