Since mass and volume are two different dimensional quantities, there is no meaning in saying that mass is greater or less than the volume.
it becomes low
it becomes more dence
The force of gravity rises.
When the water gets warmer the water becomes less dense.
If the object's original density is less than water (sponge, for example) - the density will increase. If the object's original density is greater than that of water (though I cannot think of anything that fits that category that is porous enough to absorb water), the density will decrease.
the fluid rises
the fluid rises
it becomes low
it becomes more dence
The density changes in direct proportion with the mass. A lesser mass results in a lesser density and a greater mass results in a greater density.
The density of air when it is heated decreases
The density of a fluid goes down (becomes less dense) when heat is applied.
it becomes darker and density will decrease (a)
Air becomes less dense as you climb the mountain.
The force of gravity rises.
It floats.
If there is a greater density of salt water, then there is more salt, which means it will help animals help. I have forgotten how that happens, but I answered the question.
