Remember that density is an intensive property.
00:06
So density does not change with a change to mass or volume.
00:21
So for any of these, if they change the mass or volume and they tell you the density changes, it's false.
00:29
The first one says, if you have twice the mass of a substance, you have twice the volume.
00:37
That's true.
00:40
Volume and density, sorry, volume and map.
00:43
Mass are proportional to each other.
00:46
As you increase one, you increase the other.
00:48
You double one, you double the other.
00:51
You cut it in half, you cut the other one in half.
00:53
But density stays the same.
00:59
So if you divide an object in half, you have half the mass and half the volume.
01:05
That's true...
