If you move a substance from one container to another and its volume changes, the substance is a,
a. solid
b. liquid
c. gas
d. both solid and liquid
10. for the most part, you can ignore the forces of attraction among the particles in which of the following
a. solid
b. liquid
c. gas
d. solution
11. which of the following factors affects the pressure of an enclosed gas?
a. temperature
b. volume
c. number of particles
d. all of the above

9. If you move a substance from one container to another and its volume changes, the substance is a gas. This is because, gases do not have fixed volume and shape; their shape and volume depend on the container used. 10. For most part, you can ignore the forces of attraction among the particles of gases. This is because, the forces of attraction among them is negligible. 11. Factors that affect the pressure of an enclosed gas include: temprature, volume and number of particles. Thus, the correct option is D. All these factors works together to determine the pressure of an enclosed gas.
