1. In an experiment, the volume was varied for a constant
temperature of gas. 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?

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.

What does a dashed line on a graph represent?
How can you tell the difference between a graph in which on variable is directly proportional to
another and a graph in which two variables vary inversely?
