Conceptual Gas Laws and KMT

What will happen to the volume of a balloon if you warm it up into over hot water?

• Volume will increase

• Volume will decrease

• Volume will not change

If the temperature of a gas decreases, the pressure of the gas will...

• Decrease

• Increase

• Not change

• Cannot be determined

When a cold tire is inflated to a certain pressure and then is warmed up due to friction with the road, the pressure increases. This happens because the

• air molecules hit the walls of the tire less frequently

• rubber in the tires reacts with oxygen in the atmosphere

• air molecules speed up and collide with the tire walls more often

• air molecules diffuse rapidly through the walls of the tire.

If a hairspray can is heated, what can be expected of the pressure of the gas inside the can?

• The pressure will increase

• The pressure will decrease

• The pressure will remain constant

• The pressure will equalize

What will happen to the pressure inside a balloon if you squeeze it and the volume (size) of the balloon decreases?

• Pressure will increase

• Pressure will decrease

• Pressure will not change

In an "inverse relationship", such as Boyle's Law, when one variable shows an increase the other variable...

• increases as well

• remains constant

• shows a flat line on a graph

• decreases

In a "direct relationship", such as Charles' Law, when one variable shows an increase the other variable...

• increases as well

• remains constant

• shows a flat line on a graph

• decreases

When volume increases, pressure must...

• Increase

• Decrease

Which of the following is an assumption of the kinetic-molecular theory of gases?

• Collisions between gas particles are inelastic.

• Gases consist of closely spaced particles.

• Gas particles move around in an orderly manner.

• The temperature of a gas depends on the average kinetic energy of the gas particles.

According to the KMT, gases are composed of a large number of particles that behave like hard, spherical objects. Based on this information, gas particles must always be in a state of __________________.

• solitaire

• constant, organized motion

• constant, random motion

• translucence
