Same
The mathematical relationship of Liquid pressure and Height
Direct Relationship
What can you use to predict the buoyancy of an object?
Density/Volume/Weight of Fluid Displaced
A hot air balloon weights 1600 N. How much air must it displace to float?
1600 N of air.
The phase of matter where particles move around each other and are close together.
Liquids
Which has more volume—a kilogram of lead or a kilogram of aluminum?
Aluminum
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
True or False: Buoyant Force depends on the object's volume and NOT the weight
True
Force that makes object sink
Gravity/Weight
Atoms + Atoms =
Molecules
What happens to the density of a uniform piece of wood when we cut it in half?
Nothing
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
A scientific rule that states that the buoyant force on an object is equal to the weight of the fluid displaced
Archimedes principle
The upward force that a fluid exerts on an object in the fluid
Buoyant Force
A mixture of cornstarch and water that behaves both solid and a liquid
Oobleck or Non-Newtonian fluid
A rock has a mass of 240 grams and occupies a volume of 70 cm3. What is the rock made of?
Diamond
Does pressure exerted by a liquid increase or decrease or remains the same with depth?
Increases
Why will a volleyball held beneath the surface of water have more buoyant force than if it is floating?
It displaces more water
What will happen to the object if its weight is greater than its buoyant force
Sink
How old are the atoms?
13.8 Billion Years
A rectangular block of lead (Pb) measures 2 cm X 3 cm X 4.5 cm. If the density of Pb is 11.34 g/cm3, calculate the mass of the block.
306 g Pb
What is the unit equivalent to N/m2
Pascal
The part of a fish that allows it to float or sink
Fish/Swim Bladder
