Using the picture, tell me which object is the least dense and why?

The cork because it is floating at the top of the water

The fish because he is in the middle

The rock because it is at the bottom

The cork and the rock because they have the same about of atoms.

The amount of pressure per volume

The amount of pressure per mass

How could two objects have different volumes , but still have the same mass ?

If the larger object has a lower density

If they both have the same density

If the smaller object has a lower density

If the larger object has a higher density .

How can an object float on water?

If it has the same density as water

Why do objects sink or float in H 2 O?

Because their densities are higher or lower than compared to water

Because their densities are using gravity to pull down

Because their densities are heavier or lighter

Because their mass and volumes are equal

Archimedes used density to discover if the crown of gold was real because

Substances have their own unique densities

Substances can change densities depending on their size

Substances can change densities depending on their mass

Substances can change densities depending on their volume

the amount of mass in a given space.

the amount of mass in an object

Why do objects sink or float in H 2 O ?

Because their densities are higher or lower than compared to water

Because their densities are using gravity to pull down
