Of course not.
I am assuming that you mean mass of an object. The answer is no, it does not change. Mass (Density) stays the same wherever the object is, only its weight will change if the force of gravity is different.
If you place the object into the liquid it will sink.
No
To change density there are three ways. You can change the shape, mass or volume of the object
In a simple way, since density = mass /volume, the density of an object can be changed by changing either mass or volume of an object .
The density of an object is determined by its mass and volume. If the mass of the object increases and its volume stays the same, the density will increase. If the volume of the object increases and the mass stays the same, the density will decrease.
Yes.
density
Changing the shape CAN change the density. If you change it into a smaller shape, then you increase the density. However the mass will not change.
Density is a property that depends on the mass and volume of the object, not its shape. Changing the shape of an object does not alter the amount of mass or volume it contains, so the density remains the same.
-- Make the object bigger, by inflating it, or by beating it thin and forming it into a hollow box or ball. -- Place it in a fluid that has greater density than the fluid it's in now.
density is how dense an object is (see dense) it is calculated by dividing the mass by volume of an object. density can be changed by changing the size or shape or the object
