A researcher wants to investigate the relationship between pressure and temperature in carbon dioxide gas (CO2) by using a pressure sensor on an airtight flask. image

In Step 1 of the investigation, the student adds CO2 to the flask at 20℃.

Choice Steps Taken Expected Result Graph
A.
Step 2: Turn on the hot plate to increase the temperature of the gas and record the resulting pressure.

Step 3: Repeat with different sizes of flasks to account for volume.
