Question

when two ice cubes are pressed over each other,they stick .This force responsible to stick them :
a) Dipole-Dipole Interaction
b) Van Der Wall force c) Hydrogen Bond
d) London Force

Answer 1

Correct Option - C)

Hydrogen Bonding formation is responsible to stick the ice cubes together.

Hope This Helps!

Answer 2

ANSWER:

The reason behind the sticking of two ice cubes is the formation of hydrogen bonding.

EXPLANATION:

    In the liquid form, water molecules are free to involve in hydrogen bonding. But as the ice cubes are packed tightly, they cannot change their bonding. If you observe the structure of ice, you can see that there are surface facing water molecules present.

   So when two ice cubes come in contact with each other, the surface water molecules attract of one ice cube attract the surface molecules of the other, through hydrogen bonds. This is why "ice cubes stick together" when they come in contact.
