Gases

Question 1

The diagram shows the movement of particles from one end of the container to the opposite end of the container.Which event is most likely occurring?

Revolt · Accepted Answer

effusion because there is a movement of a gas through a small opening into a larger volume

Question 2

Which is an example of the kinetic-molecular theory not holding true for a gas?

Revolt · Accepted Answer

The attraction between particles causes a gas to condense at low temperatures.

Question 3

A substance is made up of slow-moving particles that have very little space between them. Based on this information, what can most likely be concluded about this substance?

Revolt · Accepted Answer

It is not a gas because its particles do not have large spaces between them.

Question 4

Which statement about gases is true?

Revolt · Accepted Answer

They are made up of hard spheres that are in random motion.

Question 5

The closeness of particles of gas and their low speeds allow intermolecular forces to become important at certain pressures and temperatures. Which best describes this statement?

Revolt · Accepted Answer

This is a limitation of the kinetic-molecular theory.

Question 6

Which statement best describes the collisions of gas particles according to the kinetic-molecular theory?

Revolt · Accepted Answer

As particles travel in straight lines, their paths sometimes meet, and then they bounce apart with no gain or loss of energy.

Question 7

The table describes a gas stored in four different containers. Properties of Stored GasContainerProperties1· Low number of collisions with container walls· Medium average kinetic energy· Large number of particles2· Large number of collisions with container walls· Medium average kinetic energy· Small number of particles with little spaces between them3· Large number of collisions with container walls· High average kinetic energy· Large number of particles with large spaces between them4· Few collisions with container walls· Low average kinetic energy· Small number of particlesWhich container has gas stored at the highest temperature?

Revolt · Accepted Answer

3

Question 8

According to the kinetic-molecular theory, the collision between two ideal gas particles is a result of

Revolt · Accepted Answer

neither attraction nor repulsion.

Question 9

Which step will decrease the pressure of a gas inside a closed cubical container?

Revolt · Accepted Answer

decreasing the temperature inside the container
