Is the density of warm water greater than cold water?
Yes, cold water is dencer indeed
How is density used in real life?
Density has its connection with buoyancy.The ability of an object to "float" when it is placed in a fluid is called buoyant force. If an object is less dense than the fluid in which it is placed, it will "float" on the fluid. If it is more dense than the fluid, it will "sink." For example: Metal ships can float because their total density is less than that of the water that they float on.
A block of wood of mass 3.5 kg floats in waterCalculate the buoyant force on the block?
mass of the block is 3.5kg so block is floats on the water then we are say density of the body less than the water there is only along normal force acting the body buoyant force=mass*gravity B=3.5*9.8 B=34.8Kg/m/sec^2. thank you
Why is there more pressure at the bottom of the pool than at the top?
More water on TOP of you.
Why does a fork sink?
To float on water the object should have density less than that of water. But fork have density that is much more greater than that of water.Thus, a fork sinks in water.
Why is air more buoyant than water?
Air is more buoyant than water because air is less dense than water, and everything the thing that is less dense is always more buoyant than what is more dense than it.
Cold air is than warm air?
Cold air is more dense and less buoyant than warm air.
Are PFDs more buoyant in deep water than in shallower water?
yes
Are PFD's more buoyant in deep water than in shallow water?
yes
Why do chlorine dispensers float?
Because they are more buoyant than the water.
Why do objects seem to be lighter in water than in air?
Objects are more buoyant in water than in air.
Why are you more buoyant in a swimming pool or a lake than on land?
Water is denser than air.
Why do ships sink deeper in fresh water than in salt water?
Any thing from people to ships are more buoyant in freshwater than in saltwater. Buoyancy is determined by the downward and upward force of an object. Also, saltwater weighs more than freshwater, so objects are more buoyant in the heavier water.

Why you can float better in the sea than in the swimming pool?
The salinitiy of the water allows you to be more buoyant.
Why does buoyancy force change in the fluid temperature high temperature less buoyancy low temperature high buoyancy now why is that?
Buoyant force is directly proportional to the mass of the liquid that is displaced by an object that is submerged in it. The mass of a certain volume of a liquid is directly proportional to the density of that liquid. The more dense the liquid is, the greater is the buoyant force. For water that is over 4 degrees Centigrade in temperature, the warmer the water, the less dense is the water. In other words, warm (summer) water is less buoyant than is cold (winter) water, because the density of warmer water is less than is the density of cooler water. Similarly, salt water is more buoyant than fresh water, because the density (in grams per cubic centimeter, or pounds per cubic yard) of salt water is greater than is the density of fresh water.
Why does a niddle sink in water?
A metal needle will sink in water, because it weighs more than the water does, and since it is not buoyant, it sinks.
