Why do a sixteen inch candle and a thirty two inch candle burn the same number of days?

How long a candle burns depends on the length, width, the content of the wax, the drafts in the room.  So if two burn the same number of days, then they probably have some other differences besides length.

1. a candle and a match, or anything that can produce light. The light can then fill the room.\n2. 7 or should I say SEVEN without the S it's EVEN.

Both numbers would have to be a multiple of 8, yet less than 40.  That leaves 8, 16, 24, 32.  32 does not have a multiple of 48, so that leaves 8, 16, 24.  Pick the two that add up to 40.

Hi there. I have sold Partylite candles for 6 years. May be of some help. We always use the hour for every inch in diameter. If the candle is 3 inches around, let it burn for 3 hours or longer. Do you know how wide? That should help give you an estimated time?!

2 reasons really, courtesy for the next person, and if you let the alcohol level drop below the wick, the next burning will not be a burning of alcohol, but of the wick itself (and as it burns down into the alcohol burner, it can ignite the fumes, creating an explosion)\nI need to ask.. where are you that your lab is still using alchohol burners instead of bunsen burners?

Wax is mostly a blend of long straight-chain hydrocarbons (alkanes, also called olefins).  It is a waxy (ha ha) solid at room temperature, and stable.  When you light a candle, the flame on the wick begins to melt some of the wax.  The liquid wax is drawn up the wick, where it burns, being converted to carbon dioxide, water, light, and heat.  Any other chemical compounds, such as fragrances, are also released at this time, usually from the pool of molten wax around the wick.

it is because we blow birthday candles.

First 9:02,9:04,9:08,...,9:30\nSecond: 9:02.5,9:05,9:07.5,...,9:30\nLast: 9:03,9:06,9:09,...,9:30\n\nFirst and Last every 6 min\nso it will be 6,12,18,24,30\nand second will light every 5min(round),\n[6,5]=30\nso they will be light every 30min\nand your answer is 9:30

because it relies to the events which can't be measured metrically anyway. Weeks follow the approximate lunar circle, there's 365 days in a year etc.\n\nalso, imagine we would divide a day into 100 hours. 1 hour would last only 14 minutes, which would be way too few and confusing. \nIf we divided a day into 10 hours, an hour would last 2 hours and 64 minutes. this would probably be too long, and we wouldn't have enough hours to properly determine a time of day...\n\nAn hour was determined as 1/4 of the time when the shadow of a pole travels a 60 degree angle or something... i THINK. I might be wrong on this, high school phisics is a LONG time ago. \nAnyway, it was old Sumerians or Babilonians who determined it like that and ever since it wasn't changed. We're too used to these units now, we can't just change them without causing a massive MESS :D

theres some  decay equation, i think. \nyou know that   the element   will have half the original after 40 days. so its like F = I (1/2)^d/40    i think. so d is the number of dayz and I is the initial.  so if d=40 dayz  youll have half  the original. \nanyways i might be wrong so sorry if i am but if im right, then u would put 100 for I (100%) and then put d=48 and find F.\nF = 100 (1/2)^(48/40)\nF = 100 (1/2)^1.2\nF = 43.52........   % of the original left after 48 days

so... i think you have to do this: first you light one thread at both ends (let's call this thread 1), and the other (thread 2) only at one end. When thread 1 burns completely you have measured 30 min, so you light the other end of thread 2. When thread 2 is burnt you know 45 min have passed since you started this process...

If we count sundials, we are talking ancients.  Even water clocks and timed candles (with lines on them for how long it burns in an hour) are pretty ancient.

The coloring in colored candles raises the melting temperature of the wax--white candles melt at a lower temperature.\n\nIf you want to make a white candle last longer, stick it in the freezer for a while.

SOMEANTHA is correct\n\nbut if you want a quickie answer for bigger numbers\nhere is a website that will do it for you\n\nhttp://www.onlineconversion.com/length_common.htm

a candle flame consists of various regions where different temperatures are assigned to them(temperatures have been measured). \n\nThe outer part has a lower temperature than that at the centre. \n\nThe temperature range can be from 500 to about 1500 degrees celcius.

Possibly because 28 x 13 = 364.\n\nTo keep the years on an even keel, you need to have approximately 365 and 1/4 days in each year, which is why we have 365 days for 3 years running, and then the fourth year is 366 days. \n\nIn other words, there are 13 lunar cycles, plus 1 or 2 extra DAYS in a whole year - with a year being 4 seasons - so how would you deal with that if you were creating a 13 month calendar? Everything would end up out of sync! You would end up with a year that had 14 lunar cycles in it...!

First I would like to say I am sorry for your loss. I lost my grandmom just 3 months ago. Anyway, it is traditional to light candles, it's a sign of praying for them!
