hard · Enhanced ACT science
A chemist measured the pressure of a fixed amount of gas in a rigid, sealed container as temperature was varied, and separately measured pressure and volume at constant temperature for a different sample:
Experiment 1 (constant volume, 2.0 L):
| Temp (K) | Pressure (atm) |
| :--- | :--- |
| 200 | 1.0 |
| 300 | 1.5 |
| 400 | 2.0 |
Experiment 2 (constant temperature, 300 K):
| Volume (L) | Pressure (atm) |
| :--- | :--- |
| 1.0 | 3.0 |
| 2.0 | 1.5 |
| 3.0 | 1.0 |
If the gas from Experiment 2 were instead held at a constant volume of 1.0 L and warmed from 300 K to 600 K, its pressure would be predicted to reach approximately:
- 1.5 atm
- 3.0 atm
- 6.0 atm
- 9.0 atm
