Answer:
Its kinetic energy.
Explanation:
In a liquid, the molecules are so close together that there is very little empty space. A liquid also has a definite volume, because molecules in a liquid do not break away from the attractive forces. The molecules can, however, move past one another freely, and so a liquid can flow, can be poured, and assumes the shape of its container.
An increase in the temperature of a liquid causes an increase in the average speed of its molecules. As the temperature of a liquid increases, the molecules move faster thereby increasing the liquid's kinetic energy.

The evidence has to be proven to be true
The six carbon atoms form a perfectly regular hexagon. All of the carbon-carbon bonds have exactly the same lengths - somewhere between single and double bonds. There are delocalized electrons above and below the plane of the ring, which makes benzene particularly stable.
Answer:
The answers to the question are
(a) The the mg/L of H₃PO₄is 1462.05 g
(b) The molarity of H₃PO₄ in the solution is 14.92 mol/L
(c) The normality of H₃PO₄ in the solution 44.85 eq/L
Explanation:
(a) The commercially available H₃PO₄ has a concentration of 85.5 percent by weight, therefore
The mass of H₃PO₄ is found by
Density of water = 1.71 g/ml
mass of one liter of acid solution = 1.71 ×1000 = 1710 g
Therefore 85.5 % by weight of H₃PO₄ =1710×85.5/100 = 1462.05 g
Therefore we have 1462.05 g/L of H₃PO₄
Molar mass of H₃PO₄ = 97.994 g/mol
(b)Therefore the number of moles in 1462.05 g = 14.92 moles and the molarity = 14.92 mol/L
(c) The Normality = 
= 1465.05÷(1×97.994/3) = 44.85 eq/L
