When a candle burns, the energy flow diagram shows chemical energy from the wax being converted to heat and light energy through combustion. The chemical potential energy stored in the wax molecules is released as heat and light when the wax reacts with oxygen in the air. Some energy is also lost to the surroundings as thermal 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.
No, the color of the candle does not affect its burning rate. The burning rate is primarily determined by factors such as wick size, wax composition, and air flow.
Air contains oxygen, which is required for combustion to occur. When fuel is burned, it reacts with oxygen in the air to release heat and light energy. This process is called oxidation. A simple diagram can show how fuel, oxygen, and heat interact to produce combustion.
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.
Candles burn at different rates due to variations in their wax composition, wick thickness, and ambient conditions such as air flow and temperature. Some candles may contain additives to either prolong or shorten their burn time.
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.

This type of diagram is called a food chain. It illustrates the flow of energy through different organisms in an ecosystem, from producers (grass) to consumers (rabbit) to predators (fox).
