the gas volume becomes 1,000 times smaller
Yes, cold candle wax is considered a solid. It has a fixed shape and volume, and its particles are closely packed together. When heated, it melts into a liquid state.
No, candle wax is not a conductor of electricity. It is an insulator.
No, burning a candle is not reversible. When a candle is burned, the wax is melted and the wick is consumed, resulting in irreversible changes to the candle's structure.
The melted wax from a lit candle is typically referred to as "candle drippings."
A bigger jar has more oxygen inside that can support combustion, allowing the candle to burn longer before running out of oxygen and extinguishing. The larger volume of the jar also traps heat, creating a more stable environment for the flame to continue burning.

wouldn't make a difference if they were the same shape,mass,and volume
The candlestick has a density of about 8.95 g/cm3
yes.you need more air,as the candle will burn for longer in a bigger volume of air because the air contains oxygen which is needed for combustion
Assuming that the cross section of the candle is the same everywhere (as you go down, or up), the volume is equal to the base area times the height. If you have a way to find out the base area, you can divide the volume by this base area to find the height.
Yes, cold candle wax is considered a solid. It has a fixed shape and volume, and its particles are closely packed together. When heated, it melts into a liquid state.
Mass, length, volume, amount of time for which it can be lit,
There is no way to know from the question. Aniline dye would probably make it more dense, but I have no doubt that there are means to color a candle that would make it less dense.
The higher the volume, the more the flame will last.
A candle
I assume you are thinking about a situation where the jar is airtight.In this case, a larger jar will have more air in it, and therefore more oxygen; the candle will be able to burn longer in a larger jar. I would expect the time it burns to be roughly proportional to the volume of the jar.
The candle is called the Paschal candle. It is sometimes referred to as the "Easter candle."
