Gas pressure was measured after each 10 mL change. 2. Show volume on the horizontal axis (x) with a scale from ______ to ______. Show pressure on the vertical axis (y) from _______ to ________. 3. For each pair measurements, draw a point on the graph. 4. Draw a line of best fit between the points. 5. Which Gas Law does this represent?___________________ What is the relationship between volume and pressure of gas when the temperature is held constant? Use the graph to describe the relationship between the volume and pressure of a gas, when temperature is held constant. Discover What Does a Graph of Pressure and Temperature Show? 1. In an experiment, the temperature was varied for a constant volume of gas. Gas pressure was measured after each 5o C change. Convert to Kelvins. 2. Show temperature on the horizontal (x) axis with a scale from ______ to ______. Show pressure on the vertical (y) axis from _______ to ________. Label axes. 3.
