DENSITY . . CHAPTER 13 d) Budi pours some corn oil into the jar. He says it has a density of 0.97. Where 7 a) The particles of a gas move further apart when they are heated. How does does it settle? Tick () the two correct boxes. this affect the density of the gas? Above the water Below the vegetable oil b) The particles of a gas are pushed closer together when the pressure on the Above the maple syrup gas is increased. How does this affect the density? Below the maple syrup c) If the densities of two gases are measured at the standard temperature and Density of gases pressure (STP), what does it mean? 6 A teacher is demonstrating how to find the density of air. a) Here are the stages she uses but they are in the wrong order. Arrange them correctly by writing the letter of each statement in the order in which it occurs. A Put the evacuated flask on the balance. B Pour water from the flask into a measuring cylinder. Teacher comments C Find the mass of the flask. (M1) D Open the flask underwater. E Measure the volume of the water. (V) F Place the flask on the balance. G Let the water replace the vacuum in the flask. H Measure the mass of the evacuated flask. (M2) I Remove air from the flask with a vacuum pump. b) Which formula should the teacher use to calculate the density of the gas? Tick () the correct box. Density = M1 - M2/V Density = M2 - MI/V Density = M2 -V/M1 Density = M1 -V/M2 0 74 75
