Density/Volume/Weight of Fluid Displaced

100

A hot air balloon weights 1600 N. How much air must it displace to float?  

1600 N of air.

200

The phase of matter where particles move around each other and are close together.

Liquids

200

Which has more volume—a kilogram of lead or a kilogram of aluminum?

Aluminum

200

How does water pressure 1 meter below the surface of a small pond compare with water pressure 1 meter below the surface of a huge lake?

Same

200

True or False: Buoyant Force depends on the object's volume and NOT the weight

True

200

Force that makes object sink

Gravity/Weight

300

Atoms + Atoms = 

Molecules

300

What happens to the density of a uniform piece of wood when we cut it in half?

Nothing

300

Calculate the pressure exerted on the floor when an elephant who weighs 24,000 N stands on one foot which has an area of 0.4 m2.

60,000 Pa    

300

A scientific rule that states that the buoyant force on an object is equal to the weight of the fluid displaced

Archimedes principle

300

The upward force that a fluid exerts on an object in the fluid

Buoyant Force

400

A mixture of cornstarch and water that behaves both solid and a liquid

Oobleck or Non-Newtonian fluid

400

A rock has a mass of 240 grams and occupies a volume of 70 cm3.  What is the rock made of?

Diamond

400

Does pressure exerted by a liquid increase or decrease or remains the same with depth?

Increases 

400

Why will a volleyball held beneath the surface of water have more buoyant force than if it is floating?

It displaces more water

400

What will happen to the object if its weight is greater than its buoyant force

Sink
