Drew learned that glass is made from sand. He found a pile of sand, but it did not look or behave much like glass. He tried reshaping the pile of sand and pressing on it, but he could not turn it into glass. Why could Drew not make the sand into glass?

Question

Drew learned that glass is made from sand. He found a pile of sand, but it did not look or behave much like glass. He tried reshaping the pile of sand and pressing on it, but he could not turn it into glass. Why could Drew not make the sand into glass?
 A. 
Glass is solid, so the sand needed to be frozen.
 B. 
The sand needed to start out looking more like glass.
 C. 
Making glass from sand requires a chemical reaction.
 D. 
The grains of sand were too closely packed together.

GPT-4o mini · Answer

C. Making glass from sand requires a chemical reaction.

Drew cannot turn sand into glass just by reshaping or pressing it because the process of making glass involves heating sand to very high temperatures until it melts and then cooling it to form glass. This involves a transformation at the molecular level, which is a chemical process, rather than simply reshaping or compressing the sand.
