A mixture of water and oil was poured inside a graduated cylinder. The water settled at the bottom, while the oil on top. Then air is introduced in the mixture using a pipette. As shown in Table 3.2, the initial measured volumes of the water plus oil are indicated in the second column while the total volume when air was introduced is indicated in the third column. Each trial is repeated thrice, and then for each trial, the measurement of the total volume of mixture with air will be subtracted to the volume of mixture without air. Table 3.2 Data for the volume of air trapped in the water-oil mixture Guide Questions 1 point each: 1. What happens to the volume reading of water-oil when air is introduced?
