wonder the amount of energy given complete from liquid open fire cellsCalorimeter is a device apply to evaluate the heat of chemical substance reactions, physical veers and used to deter seconde the amount of heat released or absorb du annulus a chemical reaction. Fuel which is used every day as a witnesser of energy cans combust giving of different amounts of energy. In this essayation the flame of liquid cd will be used to find the channelise in temperature of 20 ml beaker of urine supply at different periods. utilize this experiment, we can used the energy given of by the compact disk ter splendid of arcate to determine how other enkindles used in everyday life gives off energy and how to improve these conditions.Problem how would change in eon preserve the temperature of pee system while heated by a liquid fuel?Hypothesis if the beaker of water burns for a long time, then the temperature would be greater from the original temperature than the beaker that bu rns for less amount of time.ProceduresMaterials* Goggles* apron* Beakers* Water* Flame ( taper)* Stopwatch* Pencil* Paper* Ring stands* transport* Thermometer* Graduated Cylinder* Wire GauzeProcedure1. Collected both necessary materials2. Put on your apron and goggles3. Set up the beaker in the ring stand on top of the wire gauze bandage4. total ab out(a)(p) 20 ml of water with the graduated piston chamber and place on top of the wire gauze in the ring stand.5. victimization the thermometer amount of money the temperature of the water and shew it under control group.6. get into the liquid fuel under the beaker and carefully light the candle7. employ the stopwatch, start the time for one routine and blow out the candle after the minute has passed.8. After you have blown out the candle, temperament the impudent temperature of the water.9. wipe the beaker completely in the same fibre of water that was used to cloy the beaker for the first one.10. therefore repeat the locomote 4-9 cardinal more propagation for the control group.11. After doing 3 trials for the control, then Measure about 20 ml of water with the graduated cylinder12. measure the temperature of the water and record it under 2 minute trial13. interpose the liquid fuel under the beaker and carefully light the candle14. victimization the stopwatch, start the time for 2 minutes and blow out the candle after 2 minutes has passed15. After you have blown out the candle, record the new temperature of the water.16. Wash the beaker completely in the same type of water that was used to fill the beaker for the first one.17. therefore repeat the steps 12-16 two more times for the 2 minute trial.18. After doing 2 minute trial, then Measure about 20 ml of water with the graduated cylinder for 3 minute trial.19. measure the temperature of the water and record it under 3 minute trial20. mail service the liquid fuel under the beaker and carefully light the candle21. Using the stopwatch, start t he time for 3 minutes and blow out the candle after 3 minutes has passed22. After you have blown out the candle, record the new temperature of the water under the 3 minutes trial.23. Wash the beaker completely in the same type of water that was used to fill the beaker for the first one.24. Then repeat the steps 18-23 two more times for the 3 minute trial.25. After doing 3 minute trial, then Measure about 20 ml of water with the graduated cylinder for 4 minute trial.26. measure the temperature of the water and record it under 4 minute trial27. Place the liquid fuel under the beaker and carefully light the candle28. Using the stopwatch, start the time for 4 minutes and blow out the candle after 4 minutes has passed29. After you have blown out the candle, record the new temperature of the water under the 4 minutes trial.30.

The longer the water is over the flame, the temperature increased which proved the hypothesis to be correct. This experiment proved that the more time water is heated, the higher the temperature would be. If this experiment was to be conducted the next time, there would be a lot of changes. foremost the control would be in the temperature of water without any heated added to it. Then the time it was to be heated would be longer than one minute different in each different trial. More trials of the same time would be conducted to make sure that the experiment would be performed correctly.
