Question

Hydrogen bonding in Water and Ice
-Ice has open structure

Answer 1

Statement:
\[volume of ice > volume of liquid water\]
Is this true
Why

Answer 2

Ice has a solid structure and has a fixed shape and volume in ice atoms are tightly packed together have strongest force of attraction between them and there are no spaces between the atoms whereas liquid water do not posess a definite shape it takes the shape of container also there are spaces between the atoms they can move and change positions whereas also atoms held together by force of attraction is weaker in water than in ice therefore ice has a greater volume than water

Answer 3

Ice is less dense than water, every water molecule is made of 1 oxygen atom bonded to two hydrogen atoms. . move around each other at a temperature of 25 degree Celsius. Now lets lower the temperature which would reduce each molecules Kinetic energy of each molecule and on average they would take less space. you would think that liquid molecules will start to pack close each other but that doesn't happen. Water has hydrogen bond. a hydrogen atom is shared equally
. in a single drop of water. hydrogen bond form extended network of molecules and they are constantly breaking and reforming.so at freezing point K.E has less energy than in hydrogen bonding.so hydrogen bond form much more frequently(hexagonal structure). Ice takes up more volume than the liquid water molecules.

Answer 4

Ice

Answer 5

They're only hexagons if you were to take a cross-section of the ice. If you were to look at the 3 dimensional structure the water molecules form tetrahedrons.

Answer 6

i forgot to mention that water molecules from a tetrahedron thanks @aaronq

Answer 7

Thank you @ASRA_SALEEM @Abmon98 @aaronq for the clear explanation
