A substance with matter that is more tightly packed will generally have a greater density compared to a substance with less tightly packed matter. Density is a measure of mass per unit volume, so substances with denser matter will have more mass in a given volume.

Down feathers are tightly packed feathers found under the outer feathers of birds. They provide excellent insulation and warmth due to their ability to trap air close to the body. Down feathers are commonly used as insulation in bedding and winter clothing.
The density of water is greater than the density of ethanol. This is partly a result of how tightly packed the molecules of the substance are.
Bricks have a higher density- the molecules are packed much more tightly.
Density is a measure of how tightly matter is packed. It is calculated by dividing the mass of an object by its volume. The higher the density, the more mass is packed into a given volume.

what is the measure if how tightly matter is packed into a givin volume of a substance
The density of an object describes how tightly packed its matter is. It is calculated as an object's mass divided by its volume. A high density indicates closely packed matter, while a low density indicates less tightly packed matter.
The word you are looking for is "density". Density refers to how tightly packed the matter in a substance is.
Feather color refers to the pigment present in the feathers, giving them their visible hue. The density of feathers refers to how tightly packed the feathers are on a bird's body, which can affect insulation and waterproofing. While both play important roles in a bird's physiology, they serve different functions in terms of camouflage, display, and flight.
