Certain things float in water because their density is less than the density of water. If something experiences more upthrust in water than its weight(upthrust>weight) or upthrust=weight, then it floats in water.
no because the more water cancels out the amount upthrust trying to lift it
There are several answering services that also have this question or similar ones on it. From answerbag.com, the question asked was: what is upthrust? The answers were: * Upthrust is the upward force exerted on an object in a fluid. It arises as a result of the difference in pressure exerted by the fluid on the surface of the object at different depth. * Up thrust is the force that pushes objects up and makes them seem to loose weight in a fluid (note - a fluid means a liquid or gas) When you are standing on the ground gravity keeps you down but upthrust stops you from falling into the earths core. In a way upthrust makes things hard!! Because if it didn't exist solids wouldn't be solid.An objects density effects how it floats. * Density = Mass * ------- * Volume * Upthrust is also called buoyancy. It is the upward force produced on an object in a fluid (such as air or water). The force is equal to the weight of the fluid displaced by the object. If that weight is greater than the weight of the object, the object will float in the fluid. If it is equal, it will sit suspended. If it is less, it will sink, but the object will weigh less than it would in a vacuum. Hence, it is easier to pick up a heavy object in water than in air - the amount of displaced water weighs more than the equivalent volume of air, therefore water produces a greater upthrust. In wiki answers the question asked was: = What does upthrust mean? = The answer was: Upthrust is a type of force that pushes upwards
Cold salty water will be the most dense.

The upthrust is the reaction force that water exerts on an object inside water. if the upthust of the water is less than the force exerted by the object, the object sinks in water, and if the upthrust is greater than or equal to the force exerted by the object, the object floats.
In tropical seas the water is warmer so it is less dense than in colder areas. The ship sinks lower in water, as cargo is loaded, to displace a greater weight of water. Fresh water also produces less upthrust than sea water.
upthrust is noting but the power of water that is used to push a thing in water
tropical fresh water produces less upthrust in winter than the North Atlantic because tropical water is warmer than the cold water of the North Atlantic. i need one more reson too though!Its also becasue salt water is denser than "fresh water" therefore it will provide a greater upthrust like with mercuary that will provide even more up thrust becase it has an even greater density
upthrust works by if you put a counter in a jug of waser slowley it should work because gravity and upthrust both together is equal so that's how it works its equal !!!
tropical fresh water produces less upthrust in winter than the North Atlantic because tropical water is warmer than the cold water of the North Atlantic. I need one more reason though: for homework tropical fresh water produces less upthrust in winter than the North Atlantic because tropical water is warmer than the cold water of the North Atlantic. I need one more reason though: for homework
no because the more water cancels out the amount upthrust trying to lift it
when water is heated, its density decreases because the molecules move farther away . as we know,upthrust in a liquid is directly propotional to its density ,the upthrust decreases
Warm water is less dense.
Upthrust is a force that pushes things up in water
True... warm water is less dense than cold water.
