UNIT 7 TEST . MATTER

What are the general properties of the matter?

• Mass and density.

• Volume and density.

• Mass and volume.

• Volume and weight.

Why does cork float in the water?(more than one correct)

• Cork,s density is lower than water density.

• Cork´s flotability is higher than volume.

• Cork,s density is lower than 1g/cm3.

• Water has less flotability than cork.

Flotability is a .........propertie of the matter.

• General

• Specific

• Special

• Interesting

This plastic bottle is opened. Why does it float and doen,t sink?(more than one correct)

• Because the water push it to up with the waves

• Because the bottle has some air inside

• Because the density of the bottle+ water inside+air inside is lower than 1g/cm3.

• Because the bottle´s mass is higher than water´s mass.
