Olympic Flame

filled crucible. We then subtracted the weight of the empty crucible from the weight of the crucible with Epsom salt to determine the mass of the Epsom salt. We then lit a bunsen burner, and manipulated the airflow to allow for the optimal (hottest) flame. We then placed the bunsen burner under a clay triangle, suspended roughly 4 cm above the nozzle of the burner. Next, the crucible with the Epsom salt was placed on the triangle, and was heated by the bunsen burner for 8 minutes. After 8 minutes, the

before you use it. Much like an oven, you can’t decide to make something at a moment’s notice with an electric cooktop since you have to wait for it to warm up. With a gas cooktop, you can turn it on and immediately you have an open flame to cook with. With an open flame, you can change the temperature up and down at any time to help cook the food faster. 3. No Power Needed There may not be many times where this is necessary, but this is certainly a benefit to gas cooktops over electric cooktops

amount of liquid from the bowl of the candle. Place it on the glass slide. Try to light it. Note the result. 6. Using a piece of aluminum foil with a slit in it, place the foil between the base of the flame and the liquid in the bowl. Note the behavior of the flame. 7. Invert a beaker over the lit flame. Make observations

the synthesis/combination reaction, a piece of copper wire and magnesium ribbon is to be heated above the Bunsen burner. Make sure the Bunsen burner is on its medium setting before placing the copper wire above the flame. The copper wire will be held by a crucible tong over the flame of the Bunsen burner; it will take a few minutes in order for the new appearance of the copper wire to become visible. The copper wire was a reddish brown and solid before being heated. After it has been heated, it became

Define rollover and discuss what stage of the fire that rollover occurs. In you description make sure you talk about what conditions must be present for rollover to occur. Rollover is when a fire or flame front rolls across the ceiling away from the fire. This occurs when fuel and air reach their flammability which mostly occurs several feet away from main body of the fire. This happens because there isn’t much oxygen above the thermal column of the fire searches for air further away and the combination

sulfate heptahydrate Procedure The crucible and cover (subsequently referred to simply as crucible) were cleaned thoroughly with the test tube brush and soap solution. The crucible was sanitized via heating. The bunsen burner was first lit at a low flame which gradually was increased over a period of 8 minutes. During the last 2 minutes of heating, the cover was tilted to allow water vapor and other remnants to escape. Henceforth, the crucible was handled solely with the crucible tongs.

Hypothesis: if I light the candles at the same time then the unscented candle will burn faster because of its properties. Control Group: The control group is the unscented candle. Independent Variable: The independent variable is the unscented candle and the scented candle (black cherry). Dependent Variable: The dependent variable is the time (30 minutes) Materials: The materials that are needed are a timer to know when 30 minutes is up and it’s time to blow the candles out. Also a lighter to light

that can be identified by the flame color. To observe the colors produced by metallic ions when vaporized in a flame and to be able to identify unknown metallic ions by doing the flame test. Answers to Questions To identify the unknowns, the student could have looked at the flame using a direct vision spectroscope and then compare and observe the lines. Also, if the student had not cleaned the wire properly, then that would interfere with the color of the flame. When using the

During the experiment, a candle was lit on fire, and the fire was like any other normal fire, but until a beaker was placed over the fire, the fire dies out within a minute. When I would light a candle at home, it would burn for one hour for every one inch of wax. For a fire to burn, it needs fuel, heat, and oxygen. For that reason, the fire takes in oxygen molecules from the air for it to burn. Therefore, when a beaker is placed over a fire the oxygen supply gets limited, and the fire uses all the

horizontally, about 5 cm from the base of the flame. The flame was blown out with a puff of air. 6. The wooden splint was moved to the smoke about 10 cm above the wick. 7. The candle was extinguished, the wax solidified and materials were cleaned up. Analysis:
