What does the kinetic theory states?

At the same temperature the object that has the most mass heats quicker.

Particles won't move if you don't apply energy to it.

Particles only move in liquids and gases.

Particles are always in motion.

A sample of oxygen gas in a closed system has a volume of 200 L at 600 K. If the pressure is held constant and the temperature is lowered to 300 K, what will be the new volume of the gas?

100 L.

200 L.

300 L.

400 L.

A 2.0 liter container of nitrogen had a pressure of 3.2 atm. What volume would be necessary to decrease the pressure to 1.0 atm?

5 L

6.4 L

6.9 L

7.2 L

21.8 L

23.2 mm Hg

23.2 L

A 40.0 L tank of ammonia has a pressure of 12.7 kPa. Calculate the volume of the ammonia if its pressure is changed to 8.4 kPa while its temperature remains constant.

60.5 L

60.5 kPa

26.5 L

2.67 L

Which of the following equations is Boyle’s Law?

$P_1V_1=\ P_2V_2$

$\frac{P_1}{T_1}=\frac{P_2}{T_2}$

$\frac{V_1}{n_1}=\frac{V_2}{n_2}$

$\frac{V_1}{T_1}=\frac{V_2}{T_2}$

What is the pressure of a car tire that had an initial pressure of 1.8 atm but was heated from 38°C to 123°C?

0.9 atm

2.3 atm

1.6 atm

3.4 atm

What causes pressure?

The walls of the container

The vacuum in the container

The collisions of the particles

Atmospheric pressure acting on the outside walls

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.

Decrease

Explosion!

Increase

Nothing
