Why is Ice less dense than water? To answer this question we need to think about this in two parts. In the first part, we need to understand how anything canfloatin water. The second part is to understand why ice floats inwaterwithout sinking. Any object floats if it has fewer mass ...
a.is less dense than liquid water b.expands relative to liquid water c.has a more organized hydrogen bonding network than liquid water d.has more space between molecules than liquid water e.all of the answers are correct Cle...
The molecules inside water (liquid or solid state) arrange themselves in a completely different way. When in liquid water, they can fill in gaps and stay closer to each other than in the ice. So, the ice is less dense than liquid water and, consequently, it can float on water. Ice ...
One gigatonne is one billion tonnes. To get a picture of how large this is, imagine a block of ice one kilometre high by one kilometer wide by one kilometre deep (okay, the edges are actually 1055 metres long as ice is slightly less dense than water but you get the idea). Borrowing ...
Ice is famously anomalous ― unlike most I solids, in its usual form it is less dense than liquid water. In fact, regular ice has so far been found to come in at least 13 different forms. Furthermore, many types of amorphous ice, without the regular molecular structure of normal ice, ...
[1] Formation process of the dense shelf water (DSW) in the Sea of Okhotsk was investigated with an ice-ocean coupled model. The hindcast through 1998–2000 modeled the anomalous ice productions being controlled by air temperature and mean ice speed over the coastal area. Ice production ...
What will happen to the object which will be less denser than water? More denser than water? The density of ice is 920 kg/m^3, and that of seawater is 1030 kg/m^3. What fraction of the total volume of an iceberg is exposed?
