B. They move more quickly and independently.
C. They move more slowly and are fixed in place.
OD. They move at the same speed and in the same direction.

Answer 1

Answer: B. They move more quickly and independently.

Step-by-step explanation:

In gases the particles move rapidly in all directions, frequently colliding with each other and the side of the container. With an increase in temperature, the particles gain kinetic energy and move faster.
