most substances change from liquid to solid form, they shrink together and denser
water changes from a liquid to solid it expands, becomes less dense At normal atmospheric pressure, molecules usually behave in predictable ways as their temperature changes. Molecules fly apart into a gas when heated, condense into a flowing liquid when cooled, and shrink into a frozen solid when chilled still further. The changes in state parallel changes in energy: from high energy to medium energy
Scientists say water's quirky behavior is caused by the shape of its molecule and by how its molecules bond to one another
water expends cooling because of hydrogen bonding.
No. Water expands when it freezes, causing the rocks to crack and break.
Only one liquid expands when heated and thats water the most common liquid.
it expands because water when it freezes becomes ice and ice expands in cold temperatures. Take a soda can for example put it in the freezer for about 20 min. it should have expanded by then. THANKS!
it remain the same as it has definite volume.
The water is known as dew.
Water shrinks on cooling upto 4o C. But on further cooling it expands.
I think that only water expands when it freezes everything else contracts
none of the above
No, most substances contract with cooling, only some exotic substances (eg water) expands when cooled.
ur joking right. well when ice expands it will fracture the cooling system. its kinda like when you fill a plastic bottle to the top with water, put the lid on and freeze it. if you dont know what i mean then try it, but for gods sake dont use glass!!!
water expands on heating and contracts on cooling because when water is heated the molecules are closely packed and they overflow but when cooled they are loosely packed therefore they dont overflow. it is as simple as that.
No. It undergoes convective cooling, rising and losing heat to the surrounding air.
The human body does not expand and contract with heating and cooling like water, Because the body usually maintains a constant internal temp (By sweating, teeth chattering, etc.)
Water turns to ice which expands
You mean FORM, correct? Well, when water (in a small crack [hairline] in a rock) turns to ice, it EXPANDS. Having no place to go, it pushes crack's sides apart thus enlarging it. Consequently, larger crack is created, eventually rock may split.
Yes it contract and the expansion from 4 to 0 degrees is due to the crystallisation of water molecules.
capillarity rise.heating expands mercury whereas cooling contracts mercury
