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.
A rock
You probaly read what i wrote earlier gregorS, if not, type in "how to find the density of a large rock" heheheheheheheh HAHAHAHAHAH MWOHAHAHAHAHAH!
stupid question. mass and volume are not interchangable. it depends on the density of the mass. a 400 gram balloon will take up more milliliters than a 400 gram rock.
rock
The heaviness of each particle. For example, a rock is made of heavier particles than a piece of cloth so if you were to get the same quantity of each item and drop it, than the rock would hit the ground first since it is more dense. An improved version: Density is a measurement that describes how heavy an object is for a given volume. For example: an object has high density if it is heavy and has a small volume (e.g. gold), and an object has low density if it is light and has a large volume (e.g. balloon).
Both a rock and a balloon have mass and volume. They both occupy space, although a rock is solid and a balloon is filled with gas.
The density of a balloon depends on the gas it is filled with. For example, a balloon filled with helium is less dense than the surrounding air, causing it to float. The density of a balloon can also be affected by additional factors like the material it is made of and any objects it contains.
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.
Body of water has large mass and volume. Rock has got less mass and volume. But still the rock sinks in the water. The reason is very simple. Density of the rock is more than water. Mass upon volume of the rock is more than water. So rock sinks in the water. That means rock is heavier than water, if the volume of both is same. Alternately the if you take the same mass of both, rock and water, volume of the rock is lesser than that of water.
We are all similar to the experiment the scientist Galileo conducted when testing the laws of gravity. He had been atop the Leaning Tower Of Pisa and had thrown objects of the different weights and they had landed on the ground at the same time. This is because gravity pulls all objects, regardless of mass at the same speed. Some factors which could alter this could be air resistance, which causes friction. So if in a room without air, i think that the balloons will fall at the same time. Normally, though, i think that aside from some circumstances, the smaller balloon will fall first. (if there is air in the big one, of course it won't fall quickly, its mass will be reduced)
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 one ton rock would weigh 2000 pounds or 907 kilograms, but the physical size can vary greatly depending on the density and composition of the rock. It could be as small as a basketball or as large as a small car.
