Rate of Vaporization Design Lab Essay
How does changing the surface theatre of a sample of pee affect the fourth dimension taken for the water to labour?Background By changing the containers of the water, the surface area of the water is thus being limited as the same volume of water is spread out everyplace smaller or larger surfaces. The measure being compared is the clock each(prenominal) sample of water ordain take before it reaches the boiling point, vitamin C C. The relationship between the surface area and this amount of time will be determined by comparing the circular area of each container to the time.The independent variable manipulated in this lab is surface area, which will be varied by filling the water into different coat containers. The dependent variable being measured is the time taken to boil in seconds. This will therein tell us the rate of boiling, a measure of the rate of vaporization. Variables that must be controlled while performing this audition include the temperature of the water an d the volume of the water.Materials petri lot analyze tube 80 mL beaker 300 mL beaker graduated cylinder 5 50 mL samples of distilled water Bunsen burner metal ring stand thermometer stop watchMethod1. Measure in cm the radius of each the petri dish, test tube, graduated cylinder, and two beakers. Calculate the area of each. 2. Pour 50 mL of distilled water into petri dish. Repeat for test tube, graduated cylinder, 80 and 300 mL beakers. 3. Set up Bunsen burner and metal ring stand. Place petri dish with distilled water on metal ring stand. Place thermometer in petri dish. 4. routine on gas / Bunsen burner. Start stopwatch.5. Measure with stopwatch the time it takes until the thermometer reads 100 C (boiling point of water). Record this time. 6. Repeat steps 1 5 four more times. 7. Repeat above procedure apply the test tube, graduated cylinder, and two beakers.
