The wax in the candle contains chemical energy. When you burn the candle the chemical energy is transferred into heat (thermal) and light energy. :)
When you cover the top of a glass with a burning candle inside, you restrict the flow of oxygen to the flame. This causes the flame to consume the available oxygen within the glass, leading to the extinguishing of the flame due to lack of oxygen. Additionally, the heat and gases produced by the burning candle may build up within the glass.
The yellow candle burns faster because of the gases and subsistances in that color.
A fire needs oxygen to burn. A fire in an enclosed space will go out if not enough oxygen is present to keep the fire going. A diagram of this type would show the air flow moving toward a fire instead of away from it.
The wax runs down the side of a candle because the heat from the flame melts the wax, causing it to flow and drip down. This effect is influenced by factors such as the type of wax, the size and shape of the candle, and the environment's temperature.
The type of wax is going to dictate the burning rate of a candle, as will the diameter of the candle. A large diameter candle will burn its length more slowly than a small diameter one. Think how fast birthday cake candles burn down.
An energy flow diagram, also known as a Sankey diagram, visually represents the flow of energy through a system. It uses arrows of varying widths to show the quantity of energy moving from one process to another.
A candle converts chemical energy stored in the wax into heat and light energy through combustion. The chemical reactions release heat and light as energy, with a small amount lost as sound and heat to the surroundings.

An energy flow diagram is normally a flow diagram showing the energy gains and energy losses of a given process. This type of diagram is often used to show the efficiency of a given system or lack thereof.
