This is only how i explained it to myself after i did the experiment, so it might not be right. Burning is the result of a combustion reaction, and combustion reactions require a certain amount of activation energy to start. When the paper is in contact with water, the energy from the open flame that would usually start the combustion reaction is transferred to the water before the paper can ignite. This raises the temperature of the water and it will eventually reach boiling point. Now when all the water has evaporated, then the cup burns because there is nowhere left for the heat to be transferred to.
A marshmallow over a bonfire is a radiant heat transfer. The marshmallows are not in direct contact with the flame but are held very close to reduce burning.
Well it is simple when you think about it reallly. The wax melting from the heat of the flame is the physical change. It will turn turn into a liquid and then later solidify.
UNDER a flame? Sure, why not? Over a flame? Close? Uhhh... NO
The burning of a candle is spontaneous because it does not require continual input of energy.
embers are surprisingly enough but anyway who really cares i mean its just a question that i am answering

Burning Flame II was created on 2002-07-29.
It is an eternalnally burning flame because it purifies our civilization.
Combustion or burning requires oxygen of the air. So, if there's no air, the flame will extinguish immediately because there's no oxygen.
The color of lithium in the flame test is red.
Oxygen is required in order for a fire to continue burning. Without oxygen a flame will extinquish itself.
Well like with any flame, the lighter the flame, the higher the temperature of the flame. If the flam is burning Yellow, it is at a higher temperature and is burning more oxygen than an orange flame is. That is your difference other than the color.
