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.
