Aerogel, i think.
It may be hydrogen.
the simple rule is that if your density is higher than the substance it will sink and if it is lower it will float density= mass divided by volume. Example:Mass 7.5g Volume:2cm3 so 7.5 Divided by 2= 3.75g/cm3 that is your density of object
dense or density
It is 100 g/cm3 which is way above the most dense element!
Dense means how much water and object will take up when placed in water.
An object floats for three reasons. One, it is less dense than the solution it is floating in. Such as a piece of wood. Two, the object contains something that is less dense than what it is floating in. Such as a baloon. Three, the shape of the object is such that it does not have enough weight to displace enough of the solution to envelop the object. Such as with any seagoing vessell.
Name the layers of earth in order from most dense to least dense
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.
Mercury has a density of 5.427 g/cm³ Earth has a density of 5.515 g/cm3 So Earth is the most dense planet. [See discussion for more information] NB: Mercury is the most dense planet in our solar system when not accounting for gravitational compression.
Osmium
No. In fact it is the most dense planet. The least dense is Saturn.
Overall yes, much of the sun's volume is gaseous material which is much lighter than the rock and metal that the earth is composed of. The density of Earth is 5.56 g/cm3 whereas the sun is 1.4 g/cm3 the earth is the most dense object in our Solar System (as far as we know)
The core is the most dense layer
The troposphere is the closest to the Earth and most dense atmospheric layer
Black Ironwood
inner core
It is neither. The densest layer is the inner core. The least dense layer is the crust.
The Earth is the most dense planet in our solar system out of all eight planets.
