Heating substances in paper cups?

[QUOTE="Cheesycheese213, post: 6391501, member: 617291"] In class, we briefly discussed those experiments where a paper cup is filled with water and heated, and the cup does not end up burning while the water is able to boil. From what I remember of what was said, although I am not sure I understood correctly, the water has a much higher specific heat capacity (4.18 J) than the paper (around 1.34 J) and so the heat energy would transfer from the cup to the water and prevent it from reaching the temperature needed? Websites etc. generally explain it similarly, although they also talk about the difference in temperatures to boil (100°C)/ignite (around 230°C?). I was wondering what would happen if a fluid with a similarly high heat capacity but a higher maximum temperature(?) than the paper was used? Would the cup eventually still catch on fire once the fluid passes ~230°C? Thanks! [/QUOTE]
