Why candle wax produces more heat than alcohol?
Candle wax has a higher energy content per unit weight compared to alcohol. When candle wax burns, it undergoes a chemical reaction that releases more heat energy than alcohol when it is burned. Additionally, candle wax burns at a higher temperature than alcohol, leading to the production of more heat.
What burns on a candle the wick or the wax?
The wick burns, not the wax. The flame melts the wax, which is drawn up the wick through capillary action and vaporizes, contributing to the light and heat from the candle.
How is a candle light produced?
A candle produces light through a chemical reaction known as combustion. When the wick of the candle is lit, the heat melts the wax around it, which then vaporizes and reacts with oxygen in the air to create a flame. The flame produces light through the process of incandescence, where the heat causes the particles in the flame to emit visible light.
What happens when you put a glass jar on a candle example?
If you place a glass jar over a candle, the heat from the flame will cause the air in the jar to heat up and expand. As the air cools down, it contracts, creating a partial vacuum inside the jar. Eventually, the candle will extinguish itself due to lack of oxygen inside the jar.
Is burning alcohol endothermic or exothermic?
When something burns it gives off heat. Therefore, it is exothermic.
Why candle wax produces more heat than alcohol?
Candle wax has a higher energy content per unit weight compared to alcohol. When candle wax burns, it undergoes a chemical reaction that releases more heat energy than alcohol when it is burned. Additionally, candle wax burns at a higher temperature than alcohol, leading to the production of more heat.
Give an example of a chemical change that produces light and heat?
you fart on a candle....
Why is candle a source of light?
because the flame from when it is lite produces heat and light
Is a burning candle exothermic reaction?
Yes, a burning candle is an example of an exothermic reaction. When the candle wax reacts with the oxygen in the air, it produces heat and light energy as byproducts. This release of heat is what makes the candle flame feel warm to the touch.
What burns on a candle the wick or the wax?
The wick burns, not the wax. The flame melts the wax, which is drawn up the wick through capillary action and vaporizes, contributing to the light and heat from the candle.
Do lamps give off heat?
As a candle burns it produces the by products that are the result of that burning [burning of the wax and the wick] For the most part these by products are Carbon Dioxide, Water and Soot [Carbon] if the candle burns with a sooty flame.
What source of energy is a burning candle?
A burning candle derives its energy from the chemical bonds within the wax. As the wax burns, it undergoes a chemical reaction with oxygen in the air, releasing heat and light energy in the process.
What produces more heat the sun or us?
The humans definitly produce more heat than the sun gram for gram the only reason it's hotter because it is bigger
How many calories of heat does it take to raise the temperature of one gram or ethyl alcohol by 1 degree centigrade?
It takes 2.46 calories of heat to raise the temperature of one gram of ethyl alcohol. Calories are the energy available from the metabolism of a food.
Is a candle good conductor of heat?
No, a candle is not a good conductor of heat because it is made of wax which is a poor conductor. The heat from the flame is transferred mainly through convection as the heated air rises.
Why does a spiral rotate when suspended over a lighted candle?
This rotation is caused by convection currents, where the heat from the candle rises and creates a flow of hot air around the spiral. The heated air rises, cools down, then sinks, creating a circular motion that causes the spiral to rotate.
Does a candle have thermal energy?
A candle has thermal energy because of it flames, the flames have heat and thermal energy is heat.
