<p>Intermolecular Forces – Supplement on Crystalline and Amorphous solids</p><p>Pre-class Assignment: Read the following definitions and answer the questions below.</p><p>Crystalline solid: A solid in which particles are arranged in lattices, regular arrangements of row and columns (not always rectangular), like a stack of billiard balls. Crystalline solids have definite and specific melting points. Examples of crystalline solids include: snowflakes, dry ice, table salt, sugar, and quartz. </p><p>Amorphous solid: A solid in which particles are arranged in randomly, like a pile of spaghetti (not a lattice structure). Amorphous solids soften then liquefy over a wide temperature range. Examples of amorphous solids include: butter, road tar, and glass. </p><p>1 - How would you classify candle wax?
