AP Chemistry
3.5 Kinetic Molecular Theory
A student calibrates a pressure sensor in a rigid, sealed chamber containing a fixed amount of an ideal gas. The gas is allowed to reach equilibrium under each condition shown.
How does the total frequency of molecular collisions with the chamber walls change when the gas is heated?
| Condition | Temperature | Chamber volume | Amount of gas |
|---|---|---|---|
| Initial | \(300\ \text{K}\) | \(V\) | \(n\) |
| Heated | \(1200\ \text{K}\) | \(V\) | \(n\) |
