I need help researching this hypothesis:

Question

"A candle will burn slower in cooler environments."

I need to research two topics and three research questions in each topic.

First topic: Candle
Questions:
(1) Composition of a candle
(2) How do candles create light?
(3) (suggestions please)

I need help thinking of a second topic relating to this hypothesis, along with some ideas of what the questions should be. Any amount of help would be appreciated, thank you.
