Question

Select all statements that describe the particles if a gas is placed in a sealed container.

A) The particles are packed closely throughout the container.
B) The particles are spread far apart throughout the container.
C) Almost all of the particles are at the top of the container.
D) All of the particles are spread evenly throughout the container.

Answer 1

Gas particles in a sealed container are spread far apart throughout the container, constantly in motion, and can adopt the shape of the container.

Step-by-step explanation:

In a gas, the particles are spread far apart throughout the container. Gas particles are constantly in motion and collide with each other and the walls of the container. These collisions are elastic, meaning there is no net loss of energy. The particles in a gas do not have a fixed shape or volume. They can flow, adopt the shape of the container, and expand or contract to fill up the available space.

Answer 2

if a gas is placed in a sealed container then the particles are packed closely throughout the container and all of the particles are spread evenly throughout the container. So, the option is B. the particles are packed closely throughout the container and D. all of the particles are spread evenly throughout the container.D.

Step-by-step explanation:

In the context of gases within a sealed container, certain characteristics about the behavior of gas particles can be identified. When a gas is placed in a sealed container, B) The particles are spread far apart throughout the container which is due to the significant distances between gas particles compared to their size. Furthermore, D) All of the particles are spread evenly throughout the container as they rapidly move and collide elastically with the walls and each other, resulting in a uniform distribution due to the process of diffusion. Statement A) is not accurate for gases as it is a description of solids, and C) is incorrect because gas particles do not cluster at the top of a container but distribute evenly due to their motion.

Therefore, B and D are the most relevant option.
