The measure of upward pressure a fluid exerts on an object is
BUOYANCY
The relationship showing that the force exerted on an object in a liquid is equal to the weight of the fluid dispaced by the object is called
ARCHIMEDES' PRINCIPLE
True or False? All fluids exert an equal buoyant force on an object.
FALSE
Sink or Float? The buoyant force is greater than the object's weight.
FLOAT
Sink or Float? The buoyant force is less than the object's weight.
SINK
Sink or Float? An object stays immersed in the liquid at the level it was originally placed.
neither - NEUTRALLY BUOYANT
How can heavy objects float?
VOLUME (ie. hollow)
Buoyancy applies to which states of matter?
GASES and LIQUIDS
Which law describes the relationship between volume and temperature of gases?
CHARLES' LAW
As the temperature of a gas increases, the volume...
INCREASES
As the temperature of a gas decreases, the volume...
DECREASES
Why does a hot-air balloon float?
BUOYANCY
The force of air particles within a container is called
PRESSURE
What are units of pressure?
psi (POUNDS PER SQUARE INCH) or Pa (PASCAL)
What is the metric unit for pressure?
Pa (PASCAL)
Which law describes the relationship between pressure and volume?
BOYLE'S LAW
Assuming a constant temperature, which will have more pressure, container A containing 5L of gas or container B containing 10L or gas?
CONTAINER A
As volume increases, pressure
DECREASES
