The substances in paraffin do not chage when a candle burns?
When candles burn, new substances form.
What is regular candle?
There are so many types of candles. When you say a regular candle, it has to be the most common form of candles. It could be a uncolored paraffin taper candle. That is the most common type of candle. When the paraffin is not colored it is slightly yellowish. A colored candle burns in a different rate depending on the color used.
Do substances in paraffin change when a candle is burned?
candles made of paraffin contain cabon and hydrogen. As it burns, they combine with oxygen to form water and carbon dioxide. . So yes, yes they do :)
Why burning candle loses weight?
Because the paraffin is converted into a liquid by heat which travels up the wick to be ignited which is then combusted and turns into a form of heated plasma then is given off as a gas.
How do you separate paraffin from water?
By filtering, paraffin is not soluble in water.
What form of energy is produced when you use the candle?
When you light a candle, it burns the wax. That is chemical energy. The thermal energy is produced as the lighted wick continue to burn the wax. It also gives out light as it burns.
How do you use the plural form of wax in a sentence?
You can use the plural form "waxes" in a sentence like this: "I have multiple waxes for different purposes, such as beeswax for making candles and paraffin wax for sealing envelopes."
Who made candles?
This is from the wikipedia article about candles:In Rome, around the first century, candles were made out of tallow and the pith of rushes. The Latin word "candere" means to flicker. The Egyptians and Cretans made the candle from beeswax, as early as 3000 BC.[7] The early candle was made from various forms of natural fat, tallow, and wax. In the 18th century, spermaceti, oil produced by the sperm whale, was used to produce a superior candle.[8] Late in the 18th century, colza oil and rapeseed oil came into use as much cheaper substitutes. Paraffin was first distilled in 1830, and revolutionized candle-making, as it was an inexpensive material which produced a high-quality, odorless candle that burned reasonably cleanly. The industry was devastated soon after, however, by the distillation of kerosene (confusingly also called paraffin oil or just paraffin). Recently resin based candles that are freestanding and transparent have been developed, with the claim that they burn longer than traditional paraffin candles. They are usually scented and oil based.
What is the verb form of candle?
To candle, past tense: Candled
How does lightning effect the plants around the area in which it has hit?
it can burn the plants and it can also give off harmful chemicals to the plant. It can also burn and die if it does not have special care to it's self. Wow... Lightning turns nitrogen into a usable form for human consumption through plants. Lightning converts the nitrogen in the air from a gaseous form to a usable form for plants. This process is called "fixation". It does not burn plants or cause harmful chemical reactions of any kind.
Is there physics in a candle?
Yes, part of physics is studying the transfer of energy from one form to another. Within the candle is chemical potential energy (think about how the candle has to burn in scented candles), when a fire source comes near enough to the candle the chemical potential energy is transferred into thermal energy (heat energy) and radiant energy (visible light energy)
Is a candle flame seen because it is luminious?
A candle flame is seen because the carbon hydrogen bonds in paraffin are being broken and energy is released as photons. The photons activate the photoreceptors in your retina to form an "image", then that image travels to the back of the brain through the optic nerve to be interpreted. The carbon and hydrogen atoms form new bonds with oxygen with their electrons in a lower energy state(as carbon dioxide and water).
