A rock
A pillow is less dense than a lead sinker. Density is defined by mass per unit volume. So, if you have the same mass (weight) of a pillow, and a lead sinker, which will take up more space (volume)? The answer is the pillow. Thus, it is LESS dense.

i have no brain how am i supposed to know?
As rock cools, its density increases. This is because cooling causes the atoms and molecules to arrange themselves in a more compact and ordered manner, leading to an increase in the density of the rock.
as is, a rock, because density is mass over volume and a hot air balloon has a lesser/similar mass (stuff) but is spread out (volume) more than a rock.
When lava cools in the ocean, it forms a type of rock called pillow basalt. This distinctive rock gets its name from its pillow-like shape that results from the rapid cooling of lava in water. Pillow basalt is commonly found in areas where underwater volcanic eruptions occur.

The density of a rock labeled as AB3 can vary depending on the specific composition of the rock. Generally, rock densities fall within the range of 2 to 3 g/cm^3. However, without more specific information about the composition of the AB3 rock, an exact density cannot be determined.
A:There is no more meaning in a heart-shaped rock than in a diamond-shaped rock, a pillow-shaped rock or a star-shaped rock - unless you want to find meaning in one of these.
A rock would sink more quickly in water with a density of 10, as higher density liquids provide more buoyant force to objects submerged in them, making it easier for the rock to overcome gravity and sink. In contrast, a liquid with a negative density would not exist in reality, as density is a measure of mass per unit volume and cannot be negative.
Soft Rock as in soft rock music.Oh! I was going to say "a rough night's sleep".
Jacob used a stone for a pillow when he slept. This event is described in the Bible in the Book of Genesis.
