[DOC] [TLE] Buoyancy - body, used, water, gas, air, substance, principle [PAR] Buoyancy is the tendency of an object to float in a fluid, such as air or water. ... the 
cooler the temperature of the liquid, the denser the solution and the greater its 
buoyancy. ... The second force is the upward pressure of the water on the block. [DOC] [TLE] Buoyancy - Wikipedia [PAR] In science, buoyancy is an upward force exerted by a fluid that opposes the 
weight of an immersed object. In a column of fluid, pressure increases with depth 
as a result of the weight of ... This pressure difference results in a net upwards 
force on the object. ..... An object whose weight exceeds its buoyancy tends to 
sink. [DOC] [TLE] What is Buoyancy - UCSB Science Line - University of California ... [PAR] Buoyancy is an upward force caused by the pressure from a displaced fluid. It is 
the force that causes wood and boats to float in water and the reason why objects 
feel ... any kind of fluid, a liquid or a gas (in this case though it's easier to picture a 
liquid, ... This means that you will have a tendency to rise (float) to the surface if... [DOC] [TLE] Predict Whether an Object Will Float or Sink: Understanding Density ... [PAR] Apr 7, 2015 ... Buoyancy is the ability or tendency of an object to float in a fluid: a liquid or a gas. 
... If you put an object underwater, there will be more pressure on the bottom of 
the object ... And this creates an upwards force. ... So if you weigh an object to get 
its mass, measure an object to calculate its volume (its size) and... [DOC] [TLE] When a body is immersed in a fluid, how is upthrust caused and why ... [PAR] Buoyant force does not have any fixed direction. (Refer to the submarine's 
working to see ... When an object is immersed in a fluid, its weight (force caused 
by the gravity) will ... is immersed, its base will be acted upon by the upward 
pressure of fluid. ... The object floats (in partial or complete submersion) if the 
buoyant force is... [DOC] [TLE] buoyancy facts, information, pictures | Encyclopedia.com articles ... [PAR] There is also the pressure of the fluid all around it, which varies with depth: the 
deeper ... at the bottom of the fluid that tends to push the "bag" upward, against 
the force of gravity. ... Often, the density of an object in relation to water is referred 
to as its specific gravity: ..... The tendency of an objectimmersed in a fluid to float. [DOC] [TLE] Buoyancy and Air Bladderspacket [PAR] C. Introduction: Buoyancy describes the tendency of a submerged object in a 
fluid to sink or to rise. ... than water, then buoyancy will be a positive upward force
. If its ... pressure on an enclosed chamber of air changes, so does its volume. 
Materials ... Once you find a packet that floats, screw the cap firmly onto the bottle. 
4. [DOC] [TLE] Chapter 13: LIQUIDS [PAR] Pressure in a Liquid.  Force per unit area that a liquid exerts on an object .... A 
floating object displaces a weight of fluid equal to its own weight. Example: A... [DOC] [TLE] The tendency or ability of an object to float.. Buoyancy The pressure ... [PAR] Buoyancy The pressure on the bottom of a submerged object is greater than the 
pressure on the top. The. ... 3 Buoyant Force The upward force exerted by a fluid 
on a submerged or floating object. ... If its density is less than the fluid it will float. [DOC] [TLE] pressure facts, information, pictures | Encyclopedia.com articles ... [PAR] Since fluids have a tendency to compensate for all objects with which they come 
into ... This is the reason why ships float: because the buoyant, or lifting, force of 
them is less ... At its surface, the air exerts downward pressure equal to 1 atm. [DOC] [TLE] What is Buoyancy and Archimedes Principle [PAR] Thus an object submerged in a fluid

Question: It's the tendency of an object to float, or the upward pressure of fluid in an object
Answer: Buoyancy
