Which form of matter has a firm and stable shape and is not fluid?

A SOLID

100

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

100

Intermolecular forces are forces of attraction ________ molecules

Intermolecular forces are forces of attraction between molecules

SOLID (or KMT)

200

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

200

300

Which form of matter has no definitely shape or volume and will expand to whatever its container is?

A GAS

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
