The molecules are moving closer together.
The molecules are moving farther apart.
The molecules are speeding up.
The molecules are slowing down.
One mole of gas contains a volume of 22.4 liters. Match the following number of moles to the equivalent volume.
2.5 moles
56 L
1 mole
22.4 L
4 moles
89.6 L

Which of the following describe gas particles? Select all that apply.
Gases can't be compressed.
Gases have a fixed volume.

Which of the following explains why a balloon will expand if it's left outside in the sun?
The molecules of air move more quickly.
The molecules increase in size.
The molecules stop hitting the wall of the balloon.
The molecules aren't colliding with each other as much.
When an aluminum can with boiling water is inverted into cold water, it implodes (or crushes) because the outside pressure is higher than the inside pressure (see photo). This is because the cold water sealed the can, which condensed the gas, which caused the volume to decrease.
True
False
Assuming all of the containers have the same number of particles with the same pressure and volume, which container has the highest average kinetic energy?
Container A
Container B
Container C
Container D
A balloon has an initial volume of 1.9 L at 21 oC. It's heated, causing it to expand to 5.7 L. What is the final temperature?
7 oC
70 oC
699 oC
609 oC
Why are gases easily compressible?
They're in constant, random motion.
They move in a straight line.
They're mostly empty space.
They have no forces of attraction with other gas particles.
223.15
323.15
100.15

How would you convert 34oC to Kelvin?
K = oC + 273
oC = K + 273
K = oC - 273
oC = K + 273
