### Objective:

During the burn process, potential energy in a candle is converted to heat energy. This scientific research project measures the amount of heat power released by a burn candle.

You are watching: What are the types of energies released when a candle burns?

### Research Questions:

exactly how much energy does a candle release once it burns? just how much potential power does a candle have?

In stimulate to begin a chemistry reaction, you must use part activation energy, such as a burning flame. The activation energy consists of potential energy being converted to a different form of energy, such together kinetic or warmth energy. In this project, you have the right to calculate the quantity of calories of heat power that a given amount that candle produces.

### Materials:

hole puncher Juice have the right to Stick or glass rod Water big can deserve to opener Candle stub scale Tin foil Thermometer Match

### Experimental Procedure:

Punch two holes, one in either side of the juice can, close to the top. Subject a stick or glass rod with the holes. This will organize the juice can over the bigger can. Add 100 ml the tap water come the juice can. Leave the water for a couple of minutes so that it reaches room temperature. Eliminate the bottom that the larger can, so that it is shaped favor a steel tube. Reduced five triangular feet in the bottom the the tube, spaced as equally as feasible around the tube. These holes will certainly let wait circulate come the candle so the it will continue to burn. Sweet the candle stub, and record its weight in grams. Stand the pipe up, and place a candle ~ above a piece of silver paper in the center of the tube. Use a thermometer to measure the temperature that the water in the juice can. Write down this temperature. Irradiate the candle, and also immediately ar the juice deserve to into the bigger can. The juice have the right to should by exposed by the rod or glass rod. Row the water in the juice have the right to with a thermometer till it reads ten degrees greater than the original water temperature. Then blow the end the candle. Weigh the candle and record the measurement. Calculate how plenty of calories of warm were delivered to the water. To execute this multiply the fixed of the water (100) by the number of degrees the temperature was elevated (25). Then divide the product by the number of grams the candle lost throughout the burn process. This will present you how many calories every gram the candle released, and therefore exactly how much potential power each gram of candle has.
