FLUIDS
VISCOSITY
-
when a liquid is heated, it's viscosity it decrease.
when a gas is heated, its viscosity it increase.
-
-
DENSITY
-
-
-
objects with a high density sink, whereas objects with a low density float.
-
PRESSURE
When the temperature is increased, the pressure also increase.
it 's expressed in Pa, or N/M2 .
-
-
if the surface area increase, the pressure decrease, whereas if the surface area decrease the pressure increase. s
-
BUOYANCY
If the gravity is greater than the buoyant force, the object sinks, whereas if the gravity is lower than the buoyant force, the object floats.
-
Buoyancy is an upward force, whereas gravity is a downward force (they are opposite forces)
