If granite were melted in the laboratory, what would be the order in which its minerals would melt. The minerals inside are:
most complete large crystallized mineral is X
next complete small cryastallized mineral is Z
next to least large crystallized mineral is Y
least crystallized mineral is W
The hint we are given is that imagine a pat of butter and a lump of sugar in a sauce pan. Add heat. Which melts first? Maintain the heat until both have melted, then turn off the heat. Which solidifies (crystalizes) first?
