The sugar you buy from a store has fairly small crystals; if you made rock candy in the experiment above, the crystals were much larger. The rock candy crystals had a long time to grow into very ordered crystal shapes. You cooled the candy-glass house so quickly the liquid sugar didn’t have time to form crystals. It’s not perfectly clean glass, because reactions while you’re heating the sugar give it a brown color.
2#( In the 1920s, the British ruled India, but the people of India wanted to rule themselves. Mahatma Gandhi led the struggle for independence, and he used nonviolent action to do so. His most famous action was the Salt March. People who live in warm climates near the ocean can “make” their own salt. They transfer seawater to shallow pools. The water evaporates, leaving the salt behind. People who lived along the coast of India during British rule made their own salt by evaporating seawater, until the British made it illegal to do so.
Sand only pours because you have lots of little solid grains. And while ﬂeece might feel soft, that’s because the fabric is ﬂexible. It bends, but it’s still solid. The atoms can still vibrate, a bit like a string on a violin vibrates, but they can’t change places with each other. Because the atoms in solids stay in the same place, solids hold their shape and don’t ﬂow to ﬁt a container. If you take a basketball and place it in a bucket, the basketball doesn’t change its shape. Solids can have all sorts of different properties, such 1UARTZ DIAMOND SAND as strength, hardness, elasticity, or the ability to bend.
