Water forms hydrogen bonds, which lock the water molecules into crystals that have less density than the distances between water molecules in a liquid state. Without these hydrogen bonds, such a difference in density would not be present.
water expands when it freezes
Ice is less dense than water at the same pressure. That is why ice cubes and icebergs float on the water.
No, it is more dense. If it were less dense it would float.
more dense
Ice cubes are less dense than liquid water, which is why they float.
Ice is less dense than water, that's why it floats.
No. In fact, ice is usually less dense than liquid water.
water's density is defined as 1g/mL. if something is more dense then it will sink due to the fact that it weighs more per volume. if something is less dense then it will float because it weighs less per volume than water. Speaking in terms of atoms, if it is more dense than the molecules are closer together and can push the water molecules out of the way (so it goes to the bottom), but less dense the water molecules push against the less dense molecules causing them to rise.

Ice is less dense than water
Water vapor is the least dense form of water because it is a gas, however, water is unique in the fact that its solid form, ice is less dense than its liquid form. This is because at freezing temperature the molecules of water expand into a crystalline lattice with a higher volume and equal mass.
A wooden block can be less dense than water.
If more dense, it will sink when put into water; if less dense it floats.
Oil IS already less dense than water.
Yes, ice is less dense than water. Ice will float on water because it is less dense than that water. Two related questions are linked below, and you can learn why ice is less dense than water by following those links.
No. Ice is less dense than water. Because ice is less dense it displaces less water and floats. Water is most dense at 4o C. any change in temperature, either up or down, lowers the density.
Easy, put a fruit in water and if it floats it is less dense than water.
