the necessary chemical reaction requires a high activation energy so it needs the extra push from being heated as opposed to leaving it a room temp
Acetone will either evaporate or ignite (catch fire) when heated. At room temperature it evaporates quickly but will do so when hot. When exposed to very high temperatures it will catch fire.
No, Holmium is stable in dry air at room temperature but is rapidly oxidized in moist air or when heated.

It's purple the colour can change slightly. isn't that just great purple it's my favourite colour ya know
Litmus at a pH of 7 (which is nominally what an NaCl solution should have at room temperature) is a kind of purple color, somewhere between the "red" acidic form and the "blue" basic form. As with many indicators, the color change happens over a range rather than at a specific pH; the range for litmus is from around 5 (red) to 8 or so (blue).

they are made from clay that are heated in a high temperature room...
