Pressure in Popcorn
Pressure in Popcorn Lab Report by Brady Pauken In this experiment, we were attempting to measure the pressure that it takes to pop a popcorn kernel while heating it in oil over a burner. We measured the mass of the kernels, and with this we will be able to determine the pressure that was necessary to pop them. The popcorn pops because of water inside of the kernels that boils and then pops because of the pressure inside. Data Table: 5 mL of water- 32.34 grams 30 kernels used in total- 4 grams Water Displacement- 8 mL of water Displaced water of Kernels- 3 mL (8mL - 5mL) Weight before popping- 120.5 grams (beaker, oil, kernals) Final Weight- 118.5 grams End result- 20 popped kernels, 10 unpopped Procedure and Work: First I found the mass of H20 loss: 120.5 - 118.5 = 2 grams I then divided this by the mass of a mole of water: 2 / 18 = 0.11 mole H20 I then calculated that 3 mL of water is .003 L of water From our work in class, I...
