well how big is the candle? which material is it made out, and how long does the candle burn?
50 btu a hr
Sure. Nuclear power plants give off effectively no gases of any kind.
The sun emits 1.2×1034 J each year.
Most air conditioning [AC] units are divided up into different types or categories. For example, windows units, packaged units, ground mounted, geothermal, and yes even some solar units are starting to appear on the market. For a specific answer I would need to know the manufacturers name and the model number of your AC. The best and easiest way to determine how many watts are in an air conditioner [or used by an AC] is to find the nameplate data from the manufacturer. For window units it is normally located on the left or right side of the unit near the grill that sticks into the house. For other types of AC units it can usually be located by just looking around. Please don't confuse BTU's and Watts. BTU's are a measure of how much cooling capacity the AC has. Watts are a measure of how much electricity the AC uses. I believe you are interested in the wattage so here is a typical example. A 12,000 BTU window type AC typically uses about 1200 watts of electricity. If your electric utility charges .10 [10 cents] per kilowatt hour it would cost about 12 cents per hours to run the AC. There are of course all kinds of variables involved; age of the AC, how efficient the compressor and fan motors are, etc. If you are talking about a whole house AC unit the sizes can also vary considerably and there are many variables to consider. A typical new home of about 1400 ft. sq. located in the desert southwest area of the US would have a 3 Ton AC unit or 36,000 BTU ground or packaged AC unit. 3500 watts - Central Air Conditioner 600-1440 watts - Window Unit Air Conditioner
True that electrical devices generate some amount of heat.
If this, ie 70%, is the total energy loss, it follows that the engine is producing 30% useful energy, so that is its thermodynamic efficiency.
candle light
In fact the candle does give off quite a lot of heat- about 1400c. Most of it is going straight up. Alot of energy is given off as light too.
maybe both
Since this air conditioner puts out 8,000 btu's it shouldnt give out any heat in the house at all .
fire is a chemical reaction
No, because candles do not give off Carbon Monoxide.
There are many btu's but the most common ones are:oxygencarbon deoxide (co2)carbon moxide(co3)water vapor (h2o)

The wax that is burnt off for light or decoration of a candle

If you place the silver candle holder into the freezer for an hour or more, the wax will chip right off.
