Temperature around a candle - Physics Stack Exchange
2017年5月14日 · It is a common observation that the temperature for same distance above a candle is more than the temperature at the side of the flame. Why does it happen? As far as I could think, at the top of a candle heat is transferred both by convection and radiation, while on the sides of the flame radiation is the only mean of heat transfer.
What is the average temperature of the flame of the candle?
2024年6月24日 · The burning temperature of a candle flame is typically between 1400-1600 degrees Fahrenheit (760-870 degrees Celsius). The temperature varies depending on the type of wax and additives in the candle.
classical mechanics - Testing the temperature of an open flame ...
2011年11月29日 · The temperature at various points can be monitored using laser spectroscopy, or spectral measurements can determine the temperature of black-body emitters in the flame (soot particles). You will likely need a high degree of knowledge about the composition of the flame for these techniques, and probably this is not really what you want to be doing.
How to use candle heat? - Physics Stack Exchange
2023年1月15日 · Temperature is not the same as heat. A candle flame has a very high temperature, but the substance which is actually hot is a thin gas. As a result, the total amount of heat being produced by the candle is quite small - a quick google search suggests that a typical candle might generate somewhere on the order of $50$ to $100$ joules of heat per ...
heat - Where is the candle hottest? - Physics Stack Exchange
2012年11月30日 · In the flame or just above the flame tip or some cm above the flame or other? Update. My question more precisely concerns the heat energy I can get from a candle. I can see that isn't necessarily the hottest part. So to make the question more accurate: From which part/point of the candle can I get the most heat energy pr. time unit?
Why do two flames kept side by side merge into a single flame?
2015年6月7日 · A candle flame is a high temperature chemical reaction between atmospheric Oxygen and gaseous 'fuel', consisting of volatilised solids - typically paraffin or bees 'wax' - that is liquefied by radiated energy from the reaction above it and drawn vertically by capillary action into the reaction zone to replace fuel that has reacted.
What are the different zones of candle flame? - Answers
2023年8月10日 · In practice, candle flames do not seem very hot (much like metal feels colder than wood at room temperature, though they are the same temperature). The outer core of the candle flame is light blue ...
Color of a flame [duplicate] - Physics Stack Exchange
2021年7月25日 · Outside the central region of the flame is the main combustion volume where the gas reaction is very efficient and lots of heat is produced which results in a high temperature (up to $\sim 2000^\circ \rm C$) and the emission of blue light. In part the blue light is due to the formation of radicals which are in an excited state and high ...
What's the $T$ around a candle? - Physics Stack Exchange
2023年2月26日 · A quick search suggests that the right order-of-magnitude estimate for a candle flame is about $\ignore{0.8}10^2\,\rm W$. When I do the experiment in my kitchen, the candle burns for about $\ignore{2}10^1\,\rm s$ , and then the gas volume in my half-liter drinking glass decreases by about seventy-five milliliters.
Does temperature affect how fast a candle will burn? - Answers
2024年10月1日 · Yes, the temperature in a room can affect how fast a candle burns. Higher temperatures can cause the wax to melt more quickly and the flame to burn hotter and faster, leading to a faster burning rate.
