Why can liquids flow?

Answer 1

In a solid there are covalent bonds between atoms. These bonds are created by sharing electrons and are very strong. This prevents atoms moving. They may only vibrate in that postion. In a liqiud, the bonds are only created by ends of molecules being partially charged. These may be polar bonds when one end has a permenant charge due to an atom having a greater attraction for electrons. The uneven charge distribution creates bonds when ends of molecules with different charges attract each other. If the molecule is symmetric then dispersion forces create temporary bonds due to a temporary charge distribution as electrons move around. These polar and dispersion forces are not as strong so the bonds break all the time and the molecules may roll around each other. In gases there aren't any bonds so the molecules just fly and bounce around.
Because the molecules are loosely packed

Answer 2

The structure of liquid is affect by the temperature. water can be liquid at very cool temperatures, while metal is liquid in hot temperatures. The higher temperature causes the molecules to move faster and brake up its harder consistency which in the end make it "flow" or move, change its shape according to its surroundings.

Answer 3

Liquids can flow because their particles are loosely packed and can move past each other. This allows them to take the shape of the container they are in and flow from one place to another. The forces between liquid particles are not as strong as in solids, allowing them to move more freely.
