Looking through water has a curved effect. When the light travels through it, the transperancy is different. If you stick a pencil into a half filled glass of water you will see that it is optimised but the direction is different.
solution:
These phase changes can be brought about by heating or cooling. ... This kind of phase change--liquid to gas--is called evaporation or vaporization. Water vapor can in turn be cooled to form liquid water. This kind of phase change--from gas to liquid--is referred to as condensation vaporization.
Condensation is the change of the physical state of matter from gas phase into liquid phase, and is the reverse of vaporization. The word most often refers to the water cycle.

Explanation:
This problem deals with balancing of chemical equations.
Every chemical equations obey the law of conservation of matter which states that "in chemical reactions, matter is usually conserved and are not produced, they are simply recombined".
Equation of reaction:
BaO₂ + H₂SO₄ ⇒ H₂O₂ + BaSO₄
Let us use a mathematical approach to balance this equation by setting up simple algebraic equations:
aBaO₂ + bH₂SO₄ ⇒ cH₂O₂ + dBaSO₄
a, b, c and d are the number of moles that will balance the equation;
Conserving Ba: a = d
O: 2a + 4b = 2c + 4d
H: 2b = 2c
S: b = d
now let a = 1
d = 1
b = 1
c = 1
we see that the equation is already balanced
