1) I'm heating sugar on the stove for candy. My friends says that the melted sugar looks plasma. A) what is the differences from the state of matter of plasma and my melted sugar? B) how could I figure out the melting point of the sugar? 2) I drop a large ring into my pool, and it sinks to the bottom. A) does the ring have density that is greater than or less than 1g/cm3? How? B) my students think that a smaller ring made of the same material would float. How would you explain to them how you know the smaller ring will sink too? C) I drop the ring into a bucket of oil, and the ring floats. Why does this happen
