resulting changes to the gas’s pressure.✔ volume.weight.

Justify your answer.

Since P • V was the same for all pressures, this student’s data was

Check all reasons why a book was used.

Did you suggest filling the balloons with less air, thereby decreasing the pressure?

Sample Justification: As weight was added to the top of a syringe, the volume of the air trapped in the syringe decreased. The weight and the surface area of the plunger were used to calculate pressure. As more weight was added, the pressure increased. The volume decreased in response.

Did you mention that adding weight increased the pressure? yesnosort of

Suppose that the student took one more volume reading of 24.2 mL but forgot to measure the pressure. Compute the pressure expected for that volume. 1.221.472.134.26 kg/cm²

Suppose that the student took one more volume reading of 24.2 mL but forgot to measure the pressure. Compute the pressure expected for that volume. kg/cm²

Based on Charles’sAvogadro’s✔ Boyle’sHess’s law, pressure and volume were expected to be inversely proportional.

Did you mention that volume decreased as the pressure increased? yesnosort of

Check all actions that change the constant k.
