Answer:
C.Melt both cubes and look for a broader range of melting temperatures. The one that melts over a broader range of temperatures is the amorphous solid.
Explanation:
Amorphous solids is one that do not have a fixed melting points but melt over a wide range of temperature due to the irregular shape hence its name. Contrariwise crystalline solids, have a fixed and sharp melting point. 
This comes in handy to solve the riddle. We can characterise the pair with the melting point property.

Answer:
pOH = -log[OH – ] 
 pH + pOH = 14

I did not understand the question but hope this help!
 
        
                    
             
        
        
        
In PV = nRT, n is the number of moles. When 8 grams of oxygen are present,
n = 8/32 = 1/4
So PV = RT/4
