An inflated hot-air balloon has much more mass,
but is much less dense, than a 5-pound bar-bell.
As a matter of fact, so is an aircraft carrier ...
it floats, but the bar-bell sinks.
An object has the most density when it has the greatest mass for its volume compared to other objects of the same material. Density is calculated as mass divided by volume, so the object with the most mass in the least volume will have the highest density.
when you are comparing 3 objects of the same volume but different masses, which ever one is the heaviest, is the most dense and the lightest is the least dense. This is because Denisty= Mass ÷ Volume and when the volumes are the same, you just need to compare the masses.
No. In fact it is the most dense planet. The least dense is Saturn.
From most dense at the core to least dense proceeding outward.
(most dense to least dense) gold, mercury, water, oxygen
The density of an object determines if it sinks or floats. If an object is more dense than the medium it is in, it will sink. If it is less dense, it will float. Therefore, the most dense things typically sink.
When heated, gases typically expand and become less dense. So, a gas would be least dense when heated.
The apple would be expected to be the least dense, followed by the balloon, and then the fish tank. Density is a measure of how much mass is contained in a given volume, so objects with more mass packed into a smaller volume are denser. In this case, the fish tank likely has the most mass in comparison to its volume.
Density has nothing to do with size. A given material will have the same density regardless of its size. A small object of a material with a high density can weigh as much as or more than a large object of a material with a low density.
the one that weighs the least do ur study island
Name the layers of earth in order from most dense to least dense
You seem to be thinking that density is the same as mass, or proportional to mass. That is not the case. Density is mass divided by volume. For example, two objects of the same material have the same density. The larger object will have more mass (in the numerator), but it will also have more volume (in the denominator).
