it indicates that the blue is the high heat the the red orange is for low heat
The flame of a candle is a source of light.
No it is not luminous!
Typically, a room temperature candle will burn faster than a cold candle. A rate of burn is determined by the wick effect. The flame heats the wax beneath the wick, pulling the wax upwards along the wick to provide fuel. The heat evaporates at the top of the flame. Wax that is cold takes more energy to heat and melt, thus slowing the rate at which the wax is consumed
Yes......
The color in the candle flame shows the fuel used. It also shows temperature. The colder part of the flame is red and the closer the color is to white is the hottest. The blue color comes from the soot of the wick.
No The temperature of the candle flame is out of the temperature range of the clinical thermometer.
yellow
Depending on the wax, and the concentrations of water of oxygen in the air, somewhere between 1,200 degrees and 1,700 degrees Celsius. The heat capacity and conductivity of air and the exhaust products of combustion, however, are both very low. In practice, candle flames do not seem very hot (much like metal feels colder than wood at room temperature, though they are the same temperature). The outer core of the candle flame is light blue -- 1670 K (1400 °C). That is the hottest part of the flame. The color inside the flame becomes yellow, orange and finally red. The further you reach to the center of the flame, the lower the temperature will be. The red portion is around 1070 K (800 °C). The reason there is this variation in a candle's flame color is because air convection pulls the warmer gasses upwards.
We cannot use a clinical thermometer to measure temperature of a candle flame because then the mercury will expand too much and the thermometer will explode.
Candle burns with a yellow flame because its an incomplete combustion. The temperature of the flame also relates to its colour and also the trace metal ions present will influence the flame colour.
yes, because if the external temperature changes to a cooler temperature, the lit candle flame gets smaller.
The temperature of a candle jar inhibits the growth of psychrotrophs, and the average temperature inside the candle jar is 30 degrees Fahrenheit.

A candle flame is seen because it consists of glowing gases.
