2. 8 17 Number of Light 11 36 Part Two: Boyle's Law Purpose: To see how pressure and velome are related to each other (keeping everything else constant). Procedures 1. Hit the reset button, 2, In the upper left comer under "Constant Parameters", select "Temperature". This will make sure that temperature will not change significantly. 3. We will need a way to measure the volume. Hit the button "Measurement Tools", Select the "Ruler" box A ruler should appear at the top of the screen. The ruler can be moved so you can measure the size of the box. This will make a good way of measuring the volume. 4. To see how the relationship between pressure and volume works, temperature and number of moles must be constant. The temperature can be held constant by selecting it in the corner. 5. Take & separate measurements over a large range of numbers without exploding the container. Table 2: Volume and Pressure of a gas with temperature constant at and Particles constant at VI Volume (nm) Pressure (atm) 1819 Questions: 1. What is the independent variable? 2. What is the dependent variable? 3. What 2 factors are being held constant
