Question

Question #18

A scientist has a container filled with carbon dioxide gas. The particles of this gas are far apart, move
quickly, and bouncing off the container walls. Then the particles slow down and collect at the bottom
the container, such that they are close together and vibrating in a rigid structure.
What caused this change?
A
The temperature increased.
B The container was opened.
C The temperature decreased.
D
None of these is correct

Answer 1

C The temperature decreased.

Step-by-step explanation:

Answer 2

C. The temperature decreased.

Step-by-step explanation:

When the particles of a gas slow down and collect at the bottom of the container, forming a rigid structure, it indicates a phase change from a gas to a solid. This change is known as deposition or condensation. It typically occurs when the temperature decreases, causing the gas particles to lose energy and transition into a more ordered and compact arrangement.
