If an object is cooled, the particles within the object will lose kinetic energy and move closer together. This results in an increase in the density of the object because the same mass is now packed into a smaller volume.
As the speed of an object increases, its density remains constant. Density is a measure of how much mass is contained in a given volume, and it does not change with the object's speed.
To know this you first need to find the density of the object and the density of the fluid on which the the object shall be kept. If the density of the fluid is more than the object's density then the object will float. The object will sink if the reverse happens.
As an object contracts, its volume decreases while its mass remains constant. This results in an increase in the density of the object since density is defined as mass divided by volume.
If an object with a density below one is placed in water, it will float. This is because the density of the object is less than that of water, causing it to be buoyant and float on the surface.
As water is cooled, its density increases until it reaches its maximum density at 4 degrees Celsius. Below 4 degrees Celsius, water begins to expand as it freezes, which is why ice is less dense than liquid water.
Nothing happens to the mass when its cooled (or heated).Mass is the same (law of Conservation of Mass).Volume can change, though, which affects density (since mass is constant).
The value of the density increase but the effect is without significance.
density changes when the substance changes.
Density usually changes when an object is heated or cooled - especially in the case of gases, or when there is a change of phase.
Higher than what ?? If the object's density is higher than the density of water, then the object sinks in the water.
The density decreases.
It is halved.
the density will increase because there will be less space
