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.
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.
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.
If you add more of the same substance to an object, the density of the object will increase. Density is calculated by dividing the mass of an object by its volume, so as you add more substance, the mass increases but the volume does not increase proportionally, resulting in a higher density.
If the volume of an object increases, and the mass remains the same, the density of the object will decrease. This is because density is calculated as mass divided by volume, so if volume increases and mass stays the same, density decreases.
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

It floats
The density will decrease because the heated metal contracts and its particles slow down.
Assuming the object is the same straight through - nothing.
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.
