A porous object absorb water and is heavier. In air the water is evaporated and the object become lighter.
Cooler material (magma) shrinks and becomes more dense. Gravity acts on this denser material more strongly because of its greater unit mass (density = Mass/volume). Lighter material rises as the heavier material displaces it below. This produces a the apparent bouyant force.
lighter
heavier by almost 1 amu
it is lighter than water.
Depends on the solute: alcohol in water is lighter, salt in water is heavier than water.
I think it would be lighter because all the moisture has gone from the substacne which would make it lighter.
The earth becomes a litle lighter and the moon becomes a little heavier.
Its a process by which denser material is separated from lighter material and is set in layers with the heavier and denser material sinking to the core and the lighter to the surface.
A centrifuge spins a material, usually liquid, at a high speed to separate the heavier components from the lighter components. The heavier components are pushed to the bottom and the lighter components stay at the top.
No. It will make it lighter because there is less material.
It is lighter by 64 pounds per cubic ft. of its volume
if its heavier than water it sinks. lighter floats

heavier because they are two different weights
lighter
It depends on what your doing with it. If your towing, heavier. If your on the beach, lighter.
