Question

Two gas jars are connected to each other, but they are separated by a closed valve. One gas jar contains oxygen, and the other is empty. What will happen when the valve is opened? (3 points)
a
Oxygen molecules will remain in their original jar because of the very high density of the oxygen molecules.

b
Oxygen molecules will remain in their original jar because there is enough space in the original jar.

c
Oxygen molecules will spread evenly throughout both jars because of weak intermolecular forces.

d
Oxygen molecules will spread through both jars because of the high molecular weight of oxygen.

Answer 1

Answer:

d) Oxygen molecules will spread through both jars because of the high molecular weight of oxygen.

Explanation:

Answer 2

Answer:

Oxygen molecules will spread evenly throughout both jars because of weak intermolecular forces.

Explanation:

Intermolecular forces hold the molecules of matter together in a particular state of matter.

Gases have the weakest intermolecular forces between them. As such, the molecules of gases are isolated from each other and they move at very high velocities.

Due to weak intermolecular forces between the molecules of oxygen gas, when the valve between the two jars is opened, oxygen gas spreads evenly throughout the both jars.
