GIVE REASON FOR YOUR ANSWER

Answer 1

the answer depends on the weight of the candle and the burning flame, ofcourse it will move due to the pressure formed by the heat produced by the flame, usually in temples, you may see that ladies or small children will place a lamp on the leaf or something, which will move when released into the water, likewise ,if thw weight of the candle is more, then no doubt that the boat or the leaf will sink!

Answer 2

I think the boat runs by the energy of the candle.
