More KMT ande density etc.

Sciencequiz 1

What can density be measured in?

Density can be measured in g/cm³ for solids, g/mL for liquids, and kg/m³

Does cutting the object in half change its density?

(Density is a characteristic property, so cutting the block in half does not change its density.

What is density of a liquid measured in?

g/mL

Density is the amount of matter in a given space?

true

The density of an object can change if the temperature changes?

true

The Kinetic Molecular Theory (KMT) explains the behavior of?

matter

What are the three main points of KMT?

• All matter is made up of tiny particles.

• These particles are constantly moving.

• The speed of the particles depends on temperature (higher temperature = faster movement).

Why can gases be compressed but solids cannot?

• Gases have lots of space between their particles, allowing them to be squeezed into a smaller volume.

• Solids have tightly packed particles, so they cannot be compressed.

What happens to the movement of particles in a liquid when it is cooled?

• The particles slow down and move closer together.

• If cooled enough, the liquid may freeze into a solid.
