ProfessorWhen 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.

What happens when you cover the top of a glass that has a burning candle inside?
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.
Do candles of different colors burn faster than white ones do they yes or no?
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.
How air helps in burning explain with diagram?
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.
Why does the candle wax run down the side of a candle?
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.
Why do candles burn at different rates?
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.
