A carrot floats in salt water but sinks in fresh water. This is because

• Salt water is more dense than fresh water
• Fresh water is more dense than salt water
• The carrot is more dense than salt water
• A larger piece of carrot has a different density

The liquids in both containers are identical, and both blocks are the same size. Therefore, what can we conclude about the densities of the blocks?

• They are the same density
• Block A is more dense than Block B
• Block B is more dense than Block A
• The blocks have no density

What state of water is the least dense between water in its liquid form and in it's solid form?

• ice (solid)
• Water (liquid)

The density of hot water

• Is greater than the density of cold water
• Is less than the density of cold water
• The same as the density of cold water
• Depends on the volume of water

The density of hot and cold water are different mainly because

• The molecules in hot water move slower and are slightly closer together
• The molecules in hot water are larger
• The molecules in hot water move faster and are further apart
• The molecules in cold water move faster and are further apart

The data table below shows the masses and volumes of three objects A, B, and C

• A and B
• B and C
• A and C

What substance has the greatest density in the graph?

• E
• F
• G
• H

Which claim explains why the different balls are floating at different levels in the beaker of water?

• Ball (a) is more dense than water. Ball c is more dense than ball (b) and (c).
• Ball (c) is denser than water and is more dense than ball (a) and (b).
• Ball (a) and (c) are denser than water and both are more dense than ball (b).
• Ball (c) is more dense than the water. Ball (c) is more dense than ball (a) and (b). Both ball (a) and (b) are less dense than water.
