Some balls can bounce on water. It is known that all balls can float on water due to the amount of air they have inside. No, balls do not bounce on water, they may move/jump from force, but this is not really bouncing. Think of it this way, the lighter the ball the easier to move, hope that helps!
because of the density of oxygen.
Salt water is more buoyant than fresh water is, because salt water is slightly more dense. -- Anything that floats in salt water will float higher than it does in fresh water. -- Anything that sinks in salt water will sink slower than it does in fresh water. -- Anything that just barely floats in salt water may possibly sink in fresh water.
I have a marker which float in water.
Yes it does float in salt water.
because thermocol is lighter than water
in water yes its density is less than density of water
No, they are not bouyant. They won't float on water, but they will float on mercury.
Because the heat supplied to thermocol is absorbed by the water inside thermocol and this continues till the temperature reach the boiling point of water. Once the temperature reaches to boiling point of water then the temperature of water inside the thermocol is same as the temperature on the outer side of thermocol facing the heat and then only the thermocol glass will start burning.
Well balls float-cos the force of upthrust from the water is pushing them up-and is stronger than gravity.The surface area increases the upthrust-which is why pumped balls float better than deflated.
A Rock would obviously sink in water and a egg would float in salt water Believe it or not bowling balls that are denser than water float!
they both float and have less density than water
The density of tennis balls is approx. 0,38 g/cm3 an can float on water.
thermocol
Take a ball cut off into half and use thermocol balls as thylakoids.
Certain WEIGHTS of bowling balls float. Bowling balls have a volume of 6250 cm3. An equal amount of water would weigh 6.25 kilograms. A bowling ball that weighs less than 6.25 kilograms--8-pound, 10-pound and 12-pound balls--will float. 14-pound and 16-pound balls, having a density higher than 6.25 kilograms, will not float.
When filled or partly filled with air, tennis balls will float. However, some of the materials in them are heavier than water. If the air is removed, some tennis balls may sink in water, as do rubber tires.
