Rate of Vaporization Design Lab Essay

How does changing the fold area of a sample of water affect the time taken for the water to travail?Background By changing the containers of the water, the surface area of the water is thus being modified as the same volume of water is spread out over smaller or larger surfaces. The round being compared is the time each sample of water will take before it reaches the boiling point, nose candy C. The relationship between the surface area and this amount of time will be obstinate by comparing the circular area of each container to the time.The independent variant manipulated in this lab is surface area, which will be varied by filling the water into different sized 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 experiment admit the temperature of the water and the volume of the water.Materials petr i dish test tube 80 mL beaker three hundred mL beaker gradatory cylinder 5 50 mL samples of distilled water Bunsen burner metal ring stand thermometer stopwatchMethod1. beak in cm the radius of each the petri dish, test tube, graduated cylinder, and two beakers. code 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. Turn 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 using the test tube, graduated cylinder, and two beakers.
