Candles

Candle wax is a physical property since it is a characteristic of the substance itself. Physical properties describe the appearance, composition, and behavior of a material without changing its chemical composition.

The name of a straight chain alkane compound contained in most candles is paraffin. It is a mix of straight chain alkane made of several atoms of carbon.

When a candle burns, the heat from the flame melts the wax near the wick. The liquid wax is drawn up the wick and vaporizes, combining with oxygen in the air to produce water vapor and carbon dioxide. This process sustains the flame until the wax is fully consumed.

We pucker our lips while blowing candles to concentrate the flow of air at the target (candles),if the lips are not puckered then it would lead to the dispersal of air and desired result might not be achieved.

White candles may burn faster than colored candles due to the presence of chemical additives in colored candles that can affect their burn rate. These additives can change the composition of the wax, wick, or flame, leading to slower burning times in colored candles compared to their white counterparts.

burning of a substance depends upon the availability of oxygen to it. as the supply of oxygen to outermost part is greatest complete combustion takes and a blue colored flame is produced! hence outermost layer is hottest

No, a candle is not a metal in the traditional sense of the word! however, candles that are colored often have some form of metal that makes up the color - cobalt creates a blue, copper creates an array from orange to green, and so on! you can always use natural elements/plants to produce colors as well as create scents that can be added to the molten candle wax! the lavender flower not only creates a beautiful purple-blue, but has a fragrance that is both relaxing sweet smelling!

Yes, a candle needs oxygen to burn. When the wick is lit, it melts the wax, which vaporizes and combusts, reacting with oxygen in the air to produce heat and light. This process is known as combustion.

Yes, boiling water can melt candle wax. The heat from the boiling water will transfer to the candle wax and cause it to melt.

When you hold the paper over a burning candle, the air around the flame heats up and rises, creating an area of low pressure. This causes cooler air from the surrounding area to rush in towards the flame, which results in the paper being drawn upwards due to the movement of air.

wax do not freeze on top of the candle because the heat on top of the candle makes it melt and as we know heat makes solid melt.

In a burning candle, regularities include continuous consumption of wax by the flame to sustain combustion, the gradual melting and pooling of wax around the wick, and the emission of heat, light, and carbon dioxide as byproducts of the combustion process.

Candles are good for many uses. One person might want them because they smell good and they decorate a room nicely. Another person might want a candle just in case the electricity has gone out and you need lighting. Candles are also good for getting rid of the smell when you are cooking.

Because the heat of the flame causes the wax melts away after a while.

Though some people tip out the hot wax causing the candle not to last as long.

You can buy long lasting candles that last like 10-20 years.

-Liviee :D

Ice and the wax of a candle are both solids at room temperature. They can both change states, with ice melting into liquid water and candle wax melting into liquid wax when heated. Additionally, both ice and candle wax can be used to cool or absorb heat in various applications.

Candles can provide some heat to a small, enclosed space but are not efficient for warming up a room. They can create a cozy ambiance and a slight increase in temperature, but for effective heating, it's better to use a heater or central heating system.

candles can produce heat when it is burnt and when it is attached to something that can be heated or which can pass current ,like iron, the heat energy is partly converted into electricity .and when the burning candles are attached to the magnetized nails, electricity is produced and it passes though the wire and the bulb is lit...candles do not provide a large amount of power but anyway it produces electricity.................guys just try it and observe

Burning a candle produces light and heat energy through a chemical reaction called combustion. The heat energy is a result of the candle wax and wick being oxidized by the flame, releasing energy in the form of heat and light.

the wick Burns but it produces heat that melts the wax

When candle wax changes from a solid to a liquid, the heat from the flame melts the wax. The heat breaks the solid wax molecules apart, turning them into a liquid that can flow. Once the liquid wax cools down again, it solidifies, forming a new layer of solid wax.

Not for humans; I read that very hungry dogs or mouses eat wax.

Yes, fragrances that contain oils can affect how evenly a candle burns, as they can clog the wick and interfere with the burning process. Fragrance oils can also impact the scent throw and performance of a candle. It's important to follow proper candle care guidelines to ensure a clean and safe burn.

A burning candle is an example of an open system because it exchanges both energy (in the form of heat and light) and mass (as the candle wax burns) with its surroundings.

The process that can change candle wax into carbon and water is combustion. When a candle burns, the heat from the flame vaporizes the wax, which then combines with oxygen in the air to produce carbon dioxide and water vapor.

No, because a wax candle does not have any magnetic pull or push.
