A graph of gas pressure versus the number of particles in a container is a straight line. Which other relationship will have a similar graph?

A
volume versus pressure, because they are also directly proportional
B
volume versus temperature, because they are also directly proportional
C
volume versus pressure, because they are also inversely proportional
D
volume versus temperature, because they are also inversely proportional
4

Which observation indicates that the kinetic-molecular theory has limited use for describing a certain gas?

A
Gas particles are acting like tiny, solid spheres.
B
Gas particles are obeying Newton’s laws of motion.
C
Increasing pressure is reducing the volume of the gas.
D
Increasing collisions of gas molecules will increase energy between them.
5

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

increasing the number of moles of gas
Option
decreasing the volume of the container
Option
increasing the speed of the gas particles
Option
decreasing the temperature inside the container
Option
6

Which two conditions can limit the usefulness of the kinetic-molecular theory in describing gas behavior?

high pressure and low temperatures
Option
high pressure and medium temperatures
Option
low pressure and low temperatures
Option
low pressure and medium temperatures
Option
7

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?

A
This is a limitation of the kinetic-molecular theory.
B
This is a postulate of the kinetic-molecular theory.
C
This describes ideal gas behavior using the kinetic-molecular theory.
D
This describes ideal gas behavior without the kinetic-molecular theory.
8

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

A
neither attraction nor repulsion.
B
repulsion from the wall of the container.
C
repulsion from other gas particles.
D
attraction between the two particles.
9

Which statement describes effusion?

It occurs when a gas passes through a tiny hole.
Option
It occurs when a liquid passes through a tiny hole.
Option
It occurs when gas molecules disperse throughout a container.
Option
It occurs when a liquid disperses throughout a container.
Option

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

A
When particles pass close enough to one another, their attractions pull them together, and then they bounce apart with no gain or loss of energy.
B
As particles travel in straight lines, their paths sometimes meet, and then they bounce apart with no gain or loss of energy.
C
When particles pass close enough to one another, their attractions pull them together, and then they bounce apart with a loss of energy.
D
As particles travel in straight lines, their paths sometimes meet, and then they bounce apart with a loss of energy.
