Are candles worse than electricity?

However, if you are using paraffin candles made from fossil fuels, then you are much worse than electric lights, since candles are exceedingly inefficient (due to their relative low temperature) at converting fuel energy to visible light energy.

Are candles more expensive than lights?

Candles are considered to be cheaper than electric powe. One advantage of using candles instead of electricity to light your home is that candles are usually cheaper, at least in most regions of our planet. You can also ask are candles or lights better? No, candles are a poor source of light, give off fumes, use up fossil fuels (paraffin is fossil fuel), and are a fire danger.

What is the power of a candle?

Candlepower (abbreviated as cp or CP) is a unit of measurement for luminous intensity. It expresses levels of light intensity relative to the light emitted by a candle of specific size and constituents. The historical candlepower is equal to 1.02 candelas. How much power does a candle make? A candle produces 80W of heat. Usually with an efficiency of around 90%. That means that 90% of the released energy is heat, whereas the rest is light. For heating, candles, therefore, have high efficiency.

Correspondingly, what is the purpose of the candle wick?

The wick is the braided cotton that conveys (or wicks) the fuel - which is the wax - to the flame. If the wick is too tall, it could supply too much fuel to the flame too quickly, creating excess smoke and soot. Accordingly, when a candle burns what chemical energy is converted? The energy transformations that occur when a candle burns are potential energy, to chemical energy, to thermal and light energy.

Why does wax disappear when burned?

When you light a candle, heat causes the wax to melt. As the candle continues to burn, it is drawn up the wick towards the flame. The melted wax then begins to evaporate as it turns into a gas. Its molecules are oxidized, releasing water and carbon dioxide into the surrounding atmosphere.
