if concrete expands when it is heated and contracts when it is cold then, does a wine bottle full of water in a freezer shrink? becuase if heating solids expand them, than cooling the solids would make them shrink or contract. and the bootle would be very cold so shouldnt it shrink?? im really confused lol. answers plz!
When water (H2O) becomes cold and freezes, it expands because the hydrogen atoms in the water form crystalline bonds with the other slow moving water molecules. As the wine bottle becomes colder, the inside surface of the wine bottle becomes colder as does the water that contacts the wine bottle; it freezes (expands) from the outside in. The ice has the same amount of mass, but has a greater volume, and therefore it is less dense--the ice floats (Density=Mass/Volume)
My dad used to use these. Nowadays, most teachers have ways of connecting their computer to the overhead projector. Personally, I don't know how myself, but if you learned how, you could just show this youtube page on the screen and watch it fullscreen.
So thats why some highway roads have those 'kathunk' bumps! Now my life is complete! ^_^

you could just hook up a computer with the internet to a projector, you could just show the youtube vids, several of my high school teachers do this
