Ships will float higher in tropical waters because as the density of a fluid decreases with a rise in temperature, so does the buoyant force that the fluid exerts on an immersed object. The buoyant force decreases because the displaced fluid weighs less at a higher temperature.
Huh, can't you float a thumbtack in water? If it sinks, it means that the amount of water displaced weighs less than the tack.
It's greater than the density of the surrounding fluid medium. For example, a balloon filled with air sinks in air -- falls to the ground -- but floats in water. For water-tight objects, it is the average density that matters. The buoyant force acting on an object submerged in water is equal to the weight of the water displaced by the object. If the object weighs more than the weight of the water it displaces, it will sink, because the buoyant force will be less than the object's true weight. If it weighs less than the weight of the water displaced, it will float. If it weighs exactly the same as the water it displaces, it is said to have neutral buoyancy and will appear to be and behave as if it were weightless. In other words, its apparent weight will be zero. As discussed in the previous paragraph, if a submerged object sinks, we know it weighs more than the water it displaced. We can therefore conclude that it is denser than water.
by dividing mass by volume you get density which is how you determine as the density increases the chance of floating decreases It will remain suspended if the mass and the volume is equal It will sink if the mass weighs more than the volume and it will float if the mass weighs less than the volume
It depends on the two materials involved. The underlying question here is what affect does temperature have on density -- because it is the relative density of an object that will determine whether it sinks or float in a liquid. Most often, the density of a material goes down with increasing temperature (in other words buoyancy goes up with temperature) -- but that is not always the case. Water is most dense at 4°C for instance, which is why ice cubes float. For any common material, it is trivial to find a graph of density versus temperature (try google.com for instance). The lower the density, the more buoyant it will be (it won't be buoyant at all in water if the density is above 1 gram/cm3 though).
This phenomenon is known as buoyancy, which is a force exerted by a fluid that opposes the weight of an object immersed in it. The buoyant force is equal to the weight of the fluid displaced by the object. As a result, the object effectively weighs less when submerged in the fluid.

The density of a floating object is related to the density of the fluid it is floating in through Archimedes' principle. If the density of the floating object is less than the density of the fluid, it will float. The object displaces an amount of fluid equal to its weight, and the buoyant force acting on it is equal to the weight of the fluid displaced.
An object sinks if it is denser than the liquid it is immersed in, causing it to displace an amount of liquid that weighs less than the object itself. Conversely, an object floats if it is less dense than the liquid it is placed in, allowing it to displace a sufficient amount of liquid to support its weight. Archimedes' principle explains this phenomenon.
According to Archimedes principle...An object immersed in water experiences a force equal to the weight of the volume of liquid displaced by it. Here the weight of liquid displaced is 15n. So, the upward buoyant force experienced by that object is 15n.
The solid object will sink because its weight is greater than the buoyant force exerted by the fluid on the object. This occurs because the object is denser than the fluid, causing it to displace less fluid than its own weight.
An object that is denser than water will sink when immersed, while an object that is less dense will float. This is because objects with higher density displace less water and therefore sink, while objects with lower density displace more water and float.
