Energy released from changing the phase of a substance from the liquid phase to solid phase can be calculated by using the specific latent heat of fusion. The heat of fusion of water at 0 degrees Celsius is 334 J/g. Calculation are as follows:
<span>
Energy = 5 grams x 334 J/g
</span><span>Energy = 1670 J</span>
The answer is metallic bonding as this bond is the one
responsible of having to provide attraction in the electrons and atoms that
could lead of having substance to be made as a glue in order to provide
definite structure and it explains the description above.
I believe it's ;
<span>one truck load is 2.5*1.5*1 = 3.75m^3 </span>
<span>7/3.75 = 1.86 loads, </span>
