Question

1.) Which of the following is not true of gases?

A. They are fluid.
B. They are low density.
C. They are usually warm.
D. They are highly compressible.

2.)
According to the kinetic-molecular theory, when a gas particle hits something, what will happen?

A. The gas particle loses no energy because the collision is perfectly elastic.
B. The gas particle loses all energy because the collision is perfectly inelastic.
C. The gas particle loses no energy because the collision is completely inelastic.
D. The gas particle loses half of its energy because the object that it collides with absorbs energy.

3.) According to the sixth postulate of the kinetic-molecular theory, a group of gas particles will have an average kinetic energy based on what?

A. the mass of the gas particles
B. the volume of the gas particles
C. the temperature of the gas particles
D. the average acceleration of the gas particles

4.) Which of the following is not a postulate of the kinetic-molecular theory?

A. Gas particles have a high force of attraction to one another or to the walls of the container.
B. The distance between gas particles is much larger than the size of the particles themselves.
C. Gas particles will always travel in a straight line until they hit a container wall or another gas particle.
D. Gases are made up of particles that act like little, hard spheres that are always moving in a random fashion.

5.) Choose the false statement.

The particles of a gas are

A. compressible.
B. always in motion.
C. relatively far apart.
D. arranged in an orderly pattern.

Answer 1

Hello there,

5.) Choose the false statement.

The particles of a gas are

Answer: D.arranged in an orderly pattern.

4.) Which of the following is not a postulate of the kinetic-molecular theory?

Answer: A.Gas particles have a high force of attraction to one another or to the walls of the container.

3.) According to the sixth postulate of the kinetic-molecular theory, a group of gas particles will have an average kinetic energy based on what?

Answer: C.the temperature of the gas particles

2.)  

According to the kinetic-molecular theory, when a gas particle hits something, what will happen?

Answer: A.The gas particle loses no energy because the collision is perfectly elastic.

1.) Which of the following is not true of gases?

Answer: A.They are fluid.

Answer 2

Answer:

1) They are usually warm.

2) The gas particle loses no energy because the collision is perfectly elastic.

3) the temperature of the gas particles

4) Gas particles have a high force of attraction to one another or to the walls of the container.

5) arranged in an orderly pattern.

Explanation:

1) The gas  are considered to be fluid and have low density due to high volume. They are highly compressible also. However there is nothing like they are usually warm. The warms of any substance depends upon the temperature.

2) According to kinetic molecular theory,the gas particles show perfectly elastic collision, which means there is no loss of energy during collision.

3) The average kinetic energy of a gas depends upon temperature. higher the temperature more the average kinetic energy.

4) The gas particles have leas force of attraction to each other or wall of container as compared to solids or liquids. The other statements are correct.

5) Unlike solids or liquids gas particles have no regular or orderly arrangements. The particles show random movement as the inter-molecular interactions are least.
