Does ice float because water becomes more or less dense when its frozen?
The structure of frozen water (ice) is less dense than the random arrangement of the water molecules in liquid water, thus ice floats because water becomes less dense when it is frozen. Because of buoyancy forces, an object placed in a liquid will float if it is less dense than the liquid and sink if it is more dense.
Why do you think water is less dense when frozen and more dense at room temperature?
because ice floats on water
Frozen water is less dense than liquid water what does this allow ice to do?
Float
What characteristics of water is most responsible for the sinking of the Titanic?
frozen water being less dense than liquid water
Why does water weigh less when frozen?
Water expands slightly when if freezes (due to hydrogen bonding) and the resulting ice is less dense than water.(Actually, the water still weighs the same- it just takes up more space when frozen)
When a substance freezes does its density change?
Yes. When frozen, water expands becoming less dense. (That's why ice floats in water ... even in ice-cold water.)
Is hot water denser than frozen water?
Yes, water is unique in that it is the only substance that expands when frozen. Therefore ice will be less dense in terms of water molecules than room temperature water or heated water
Why is water less dense in frozen form than liquid?
Under 4 0C the volume of water increase and also the density decrease.
Is frozen water more dense?
no it isnt
Is water denser when it's frozen than when liquid?
No. I*f it were, ice would sink in a glass of water. As water freezes, it expands, and becomes less dense.
Why is frozen water so unique?
Water is the only substance that the solid form is less dense than the liquid. This means that it floats. This is very useful because otherwise, the whole ocean would be frozen!
Is ice less dense or more dense than water?
no
