Explanation:
The density of a solid copper is 8960kg/m^3 while the density of a molten copper is 7900kg/m^3 this is due to the difference in the state of matter, the solid copper is in solid state while the molten copper is in form of a liquid. In the solid copper atoms are tightly pack while they atom are not tightly packed.

= Refraction index of water = 1.333
= Refraction index of air = 1
= Angle of sunlight = 30°
From Snell's law we have

The angle measured from the vertical does the sunlight strike thesurface of the water is
