Is iron heavier or lighter than aluninum?
Iron is more dense.
Is argon lighter than air?
No Argon is not lighter than air. Argon is 25% more dense than air.
Is lead lighter substance than aluminum?
No, lead is more dense than aluminium.
When describing something is less or more dense why aren't lighter and heavier sufficint descriptors?
Because lighter and heavier refer to an objects weight - which has nothing to do with density ! For example - a kilo of feathers is heavier than half a kilo of lead - but lead is more dense !
How do differences in the air density cause convection?
Less dense rises, more dense drops down.
How do differences in air density cause convection?
Less dense rises, more dense drops down.
Is a pint of milk more dense than a pint of cream?
Cream is lighter than milk Fat is lighter than water and floats. The cream raises to the top.
Why are dense minerals more likely to form placer deposits than less dense minerals are?
placer deposits from where water is moving fast enough to move lighter materials.
What is lighter zinc or aluminum?
Aluminium. Zinc is around two and a half times heavier (more dense) than Aluminium.
What happens if density is not continuously increases from atmosphere to the core?
The less-dense substance beneath the more-dense substance will likely either become compressed (increasing its density) or break through the more-dense layer above it. A gravitationally significant object, such as a planet or star, is unstable if it has layers or pockets of less-dense material beneath more-dense material. It is believed this situation precipitates in stars as the near supernova; stars undergo fusion, which combine lighter (less-dense) elements (like hydrogen) into heavier elements (more-dense), but in supermassive stars (of a size to generate a supernova), this can cause layer or pockets of heavier atoms above lighter ones especially as the fusing atoms within the star are fused beyond iron (at which point fusing atoms consumes energy instead of producing it). On planets, this situation will tend to lead to collapses (such as sinkholes), or eruptions if the less-dense substance is liquid.
Why does a swimmer feel lighter while swimming?
You feel lighter in water because water is heavier then air and nearly all of you is heavier then air, however when you get into the water parts of you want to float to the surface putting you under the impression that you are lighter.
Do different densities cause layering?
In most cases, yes. The more dense compound(s) will sink to the bottom, while the lighter (and for our purposes) less dense ones will stay near the surface. If you're speaking from a geological stand point,(eg. - sedimentary rocks) then no, most of the layering is NOT a product of different densities.
