According to the KMT, increasing the temperature of particles will

• give off energy

• increase motion

• decrease volume

• increase pressure

How doe the particles in a gas behave?

• Neatly organized without any movement.

• Move around trapped in a small volume and with the same surrounding particles.

• Move fast enough to break attractions and pushing other particles out of the way.

• Move freely in a straight line until they collide with another particle.

When particles in a gas collide, they change

• direction and velocity

• velocity and temperature

• direction and volume

• volume and temperature

According to the kinetic molecular theory, the volume actually occupied by the molecules of a gas is negligibly small; the vast majority of the volume of the gas is empty space through which the gas molecules are moving.

• True

• False

Pressure is caused by:

• Gas molecules colliding with surfaces

• Gas molecules reacting with each other

• Gas molecules colliding with each other

• Gravity

Which of the following is NOT a part of the kinetic molecular theory?

• Gas particles are separated by large distances relative to their size

• Gas particle move in random and stright-line motion

• Gas particles have no attractive forces

• Gas particles stay close together and collide often

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.

Collisions between gas particles are said to be "elastic" because _________________________.

• they have a stretchy waistband
• kinetic energy is lost between particles
• kinetic energy is not lost between particles and is instead transferred
• particles move in a straight line
