a) i) To complete the table, we read the volumes from the diagrams. In Fig. 3, Diagram A shows the initial setup. The measuring cylinder contains 50 cm^3 of air. In Fig. 3, Diagram B shows the setup one week later. The water level has risen to the 10 cm^3 mark, indicating that 10 cm^3 of gas remains. | | | |---|---| | Volume of gas in A | 50 cm^3 | | Volume of gas in B | 10 cm^3 | ii) Step 1: Determine the initial and final volumes of gas. Initial volume of gas (from A) = 50 cm^3 Final volume of gas (from B) = 10 cm^3 Step 2: Calculate the decrease in volume. Decrease in volume = Initial volume - Final volume = 50 cm^3 - 10 cm^3 = 40 cm^3 Step 3: Calculate the percentage decrease in volume. Percentage decrease = Decrease in volumeInitial volume × 100\% = 40 cm^350 cm^3 × 100\% = (4)/(5) × 100\% = 0.8 × 100\% = 80\% The percentage decrease in the volume of gas in the measuring cylinder after one week is 80%.
