Formula & Methodology
Charles’ Law states that the volume of a gas is directly proportional to its temperature in Kelvin, provided that pressure remains constant. The formula is V1/T1 = V2/T2.
Real-World Examples
| Initial Temp (K) | Initial Volume (L) | Final Temp (K) | Final Volume (L) |
|---|---|---|---|
| 300 | 10 | 200 | 6.67 |
| 300 | 10 | 400 | 13.33 |
Data & Statistics
| Temperature (K) | Volume (L) | Pressure (atm) |
|---|---|---|
| 300 | 10 | 1 |
| 200 | 6.67 | 1 |
Expert Tips
- Always ensure the pressure remains constant for accurate results.
- For more precise calculations, consider using the ideal gas law.
