Why does ice stick to your skin?

Why does ice stick to your skin? • If the ice is cold enough

Why does ice stick to your skin? • If the ice is cold enough it will absorb enough heat from the water on your hand the moisture in your hand, for the water to freeze, and for some of the moisture in your skin to freeze. • These two form a solid bond to the ice.

Formation of Ice • To know about why ice stick to your skin we

Formation of Ice • To know about why ice stick to your skin we have to first know about the formation of ice. • On the outer level we say that when we cool the water to certain temperature it turns to ice but on molecular basis it is something different.

Molecules of Water a Tetrahedron. • We know that the water (H 2 O)

Molecules of Water a Tetrahedron. • We know that the water (H 2 O) is made up of two atoms of hydrogen and one atom of oxygen. • But oxygen has the two extra pairs of electrons which are known as lone pairs. • And they make the molecules of water a tetrahedron.

Hydrogen Bonding • When one of the lone pairs of oxygen goes out and

Hydrogen Bonding • When one of the lone pairs of oxygen goes out and attaches with the hydrogen atom of the other neighboring molecule then the interaction of molecules start which is known as the hydrogen bonding. • Every molecule in the water is attached with the nearby molecule through hydrogen bonding.

Water Flow • So when the water is in liquid state every molecule change

Water Flow • So when the water is in liquid state every molecule change its interaction and move on making new connection with new molecule which results in water flow.

Three Dimensional Hydrogen Bonding • But when temperature is very low in the case

Three Dimensional Hydrogen Bonding • But when temperature is very low in the case of ice it cannot break old connection and form new one. • Now the molecules are not in the condition to change their interactions so it remains on one place forming a three dimensional hydrogen bonding.

Why does ice stick to your skin? • On the surface of ice some

Why does ice stick to your skin? • On the surface of ice some oxygen atoms and hydrogen atoms are left facing outwards which causes them not to connect with the other molecules to form hydrogen bond. • So they are looking for a partner to form the bond and when a surface that is able to form this bond comes in contact with the ice surface it will stick to that, like our skin. • Our skin has high moisture content and very appropriate to form the bond with these atoms that is why it sticks to your skin.
