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 .
You can change the density of a substance by changing its volume. Density is equivalent to mass over volume. So changing the volume affects density.
Heat will cause expansion and hence the volume will increase. As density = mass/volume this will result in a decrease in density.
The density of an object doesn't change if you don't change the object. if you compress it or expand it, it will always have the same density.
change the temperature
how to increase density
Yes, heat will reduce the density.
Density depends on the temperature.
It won't change. Density is volume divided by mass, so if volume doesn't change, density doesn't change unless you change the mass of the object.
1 I'm not sure that this is true-- at least without some qualifications. If an object's shape is changed in such a way that it will enclose one or more pockets of air, some other substance, or even vacuum, the object's over-all density may change. If no pockets are formed, then the density probably is not changed 2 Density is the ratio of mass to volume.
This is a physical change.
No density of a object (mostly solids) never change not even when gold is in a ring or a necklace. Because in my science book it states "Density is a physical property of a substance. Density is the same for a substance no matter how much it is measured"
The concentration of matter in an object is called the density.
Heat or cool the object and this will cause a density change.
Displacement is the overall change in position
No
To change density there are three ways. You can change the shape, mass or volume of the object
Yes.
density
Change the temperature.
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.
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.
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
Adding heat to the object if the object is a solid.
