The water molecules expand when the temp. drops.
because ice floats on water
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.
frozen water being less dense than liquid water
Yes, frozen water (ice) is less dense than liquid water, so it actually increases in size when melted. This is why ice cubes float in liquid water.
Dense water sinks in comparison to less dense 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
Under 4 0C the volume of water increase and also the density decrease.
Icebergs are less dense than water because they are made mostly of frozen freshwater, which has a lower density than liquid water. This causes icebergs to float in water with a portion of their mass sticking out above the surface.
no it isnt
No. I*f it were, ice would sink in a glass of water. As water freezes, it expands, and becomes less dense.
Ice is less dense than water. When water freezes into ice, the molecules arrange themselves in a pattern that makes ice less compact, causing it to take up more space and be less dense than liquid water.
Frozen water (ice) is less dense than liquid water, which is why it floats. When water freezes, its molecules form a crystalline structure that causes it to expand, unlike most liquids that contract when they freeze. This expansion is why ice floats on water.
