B: Painting over a metal surface in order to prevent rust is known as
rust proofing and it works by preventing oxygen and water from reaching
the metal surface thus preventing a redox reaction which would result in
rusting.
Answer : The amount of heat released, 45.89 KJ
Solution :
Process involved in the calculation of heat released :

Now we have to calculate the amount of heat released.
where,
Q = amount of heat released = ?
m = mass of water = 27 g
= specific heat of liquid water = 4.184 J/gk
= specific heat of solid water = 2.093 J/gk
= enthalpy change for fusion = 40.7 KJ/mole = 40700 J/mole
conversion :
Now put all the given values in the above expression, we get
(1 KJ = 1000 J)
Therefore, the amount of heat released, 45.89 KJ
It bonds to skin because
solid polymer requires the presence of water to get things started, be it in the air or on your skin. Without a little moisture, SuperGlue can't bond anything. This explains why the glue is so good at sticking fingers together.
