True or false?
The particles in a solid are constantly in motion
TRUE due to the Kinetic Molecular Theory which states that particles are always in motion

Which form of matter conforms to its container and keeps its volume?
A LIQUID
200
True or false?
Gas particles do not move when they are inside a container
FALSE because particles are always in motion according to the Kinetic Molecular Theory

300
True or false?
Hydrogen bonding is the strongest type of intermolecular force
TRUE because of the electronegativity difference (Ex. In water, oxygen has a strong pull for electrons, hydrogen has a weak pull for electrons)
300

Kinetic Molecular Theory or Gas
400
What is the correct vocabulary word for this definition?
The forces of attraction BETWEEN molecules such as London dispersion forces, dipole-dipole bonding, and hydrogen bonding
Intermolecular forces or IMFs
400
True or false?
When a solid melts into a liquid, the particles in a liquid move faster than the particles as a solid
TRUE because particles in a liquid can flow but particles in a solid just vibrate
400
Strong _________________ will hold particles tightly together, affecting how fast or slow the substance will evaporate.
Strong intermolecular forces will hold particles tightly together, affecting how fast or slow the substance will evaporate.
400
Which vocabulary word best describes this picture?
Intermolecular forces or hydrogen bonding
500
What is the correct vocabulary word for this definition?
An argument that states that particles are constantly moving
Kinetic Molecular Theory or KMT
500
True or false?
If a substance's intermolecular forces are strong, the substance is more likely to evaporate
(Hint: Think back to the evaporation demo)
FALSE. If there is a strong bond, the strong bond will keep the particles in place and will not allow the particles to move too freely too quickly
