Water drops stay together on wax paper and don’t break apart easily. This is mainly because:

Water molecules are small

Water molecules are in motion

Water molecules are attracted to each other

Water molecules are wet

When you bring two drops of water near each other and allow them to touch, they combine immediately and become one drop. This is mainly because:

Water molecules are made of atoms

Water molecules are attracted to each other

Water molecules are magnetic

Water is a liquid

If you put food coloring in room temperature water, the coloring spreads throughout the water. The water causes the color to spread mainly because:

Water molecules are warm

Water molecules are in motion

Water is more dense than food coloring

Food coloring molecules are small

Food coloring spreads out faster in hot water than in cold water. This is mainly because:

The water molecules in hot water move more quickly

The molecules in hot water are larger

The food coloring molecules are small

Hot water is less dense

When a thermometer is heated, the red liquid inside the thermometer moves up. This is mainly because:

The red liquid is thin

The molecules of the liquid move faster and get a little further apart

Hot liquid is lighter

The glass of the thermometer gets hot

When a thermometer is cooled, the red liquid inside the thermometer moves down. This is mainly because:

Cold liquids sink

The glass of the thermometer gets cold

The molecules of the liquid move slower and get a little closer together

The red liquid is thick

To describe a liquid, you could say:

The particles of a liquid are attracted to one another but don't move

The particles of a liquid vibrate, are able to move past one another, and are attracted to one another

The particles of a liquid are not attracted to one another and are very far apart from each other

The particles of a liquid vibrate but don't move past one another

The molecules of the liquid inside the thermometer increase in speed when the thermometer is _______ .

heated

cooled

turned upside down

frozen

What happens when a liquid is heated?

the particles of the liquid get bigger

the particles get closer together

the total number of particles increases

the space between the particles increases

10.

What happens to the kinetic energy of liquid particles when cooled?

the average kinetic energy increases

the average kinetic energy decreases

the average kinetic energy stays the same

the kinetic energy changes into chemical energy

11.

Particles in a solid are arranged in ________ while particles of a liquid are arranged in ________.

Clusters, Rows

Rows, a random & scattered pattern.

loose Rows, Tight Rows

A Circle Pattern, A clustered patter n

12.

When explaining the movement of particles in a solid versus a liquid, you would say...

Particles in a solid do not move, while particles in a liquid vibrate in place.

Particles in neither a liquid or solid will move at all.

Particles in a solid will vibrate in place while particles in a liquid move continually in a random arrangement.

Particles in a solid move fluidly all throughout the objects surface and liquid particles move in a circular motion only.

13.

In the Metal Ring and Ball demonstration, the reason the metal ball did not fit through the ring after it was heated is because...

When particles of a solid are heated, they vibrate faster creating more space between them.

The volume of the particles increased.

The particles of the metal ball were both attracted to each other and moved farther apart from each other.

All of the above is true.
