O.J. Simpson, also known as âThe Juiceâ, is a former professional football player that was a member of the NFL for the Buffalo Bills and San Francisco 49ers. After being selected with the first overall pick of the 1969 NFL Draft, Simpson dominated the league at running back and became the first athlete to rush for more than 2,000 yards in a season.
water does expand when it freezes because water is polar and so pushing the molecules close together actually makes them feel a force of repulsion, hence they move apart, so it expands. In general, materials expand when heated and contract when cooled...you are trying to apply the logic that if water expands when its cooled then it must contract when heated...but this is only true between the liquid and solid states. If you heat water to be a gas (steam) then it expands just like normal materials do when heated. When heated you put more energy into the atoms so if you put them in a box it will push harder against that box (which you see as pressure) or if you allow the box to expand then it will to equalize the pressure (i.e. expanding makes the pressure less).
The volume of water changes when the water changes state from a liquid to a solid because of the formation of hydrogen bonds within it. The bonds, which are weak, are always p â¦ resent to some degree in the liquid, but as water goes solid, the formation of hydrogen bonds sets up a molecular arrangement in the water. The bonds force the water molecules into a solid structure and they push the molecules apart to do that. The extra space the water molecules then take up makes the ice less dense than the water from which it formed. That is why ice is less dense than water, and why it floats on water as we see it does. Why does the volume of water change when it freezes? That is because the gas particle's are traped in the ice
