it gets denser
The density does not change, as density is the amount of material in a given amount of space. But each piece has the same amount of space and material relative to each other.
No change: Density is a property of the substance (physical property), which is not changed by the amount of substance.
The density will be 50 % from the initial value.
It changes the amount of light going through the hole in the stage.
optical density is the amount of light
The density does not change, as density is the amount of material in a given amount of space. But each piece has the same amount of space and material relative to each other.
The density will change if the amount of matter in the same volume changes. You can have more matter wihtout changing the density, if the matter occupies more space.
No change: Density is a property of the substance (physical property), which is not changed by the amount of substance.
Nothing happens if the volume is also allowed to increase.
solid
density of a substance and volume of a substance
Gases can change their volume and that causes the density to change. Liquids and solids are practically incompressible. Their volume change under pressure is such a small amount that their density changes very little if at all.
The light is absorbed and change to tiny amount of heat

The amount stays the same but some of it changes to steam and water vapour and it will disappear.
By increasing a materials confining pressure, by decreasing a material's temperature, and by decrease the amount of the space it takes up.
