Introduction
Charles' Law is a fundamental principle in chemistry that describes the relationship between the volume and temperature of a gas. The law states that, at constant pressure, the volume of a gas is directly proportional to its temperature in Kelvin. In this article, we will explore the mathematical equations that govern Charles' Law and apply it to a real-world scenario.
Mathematical Equations
The mathematical equation that describes Charles' Law is:
V1 / T1 = V2 / T2
Where:
- V1 and V2 are the initial and final volumes of the gas, respectively
- T1 and T2 are the initial and final temperatures of the gas, respectively
Real-World Application
To further illustrate the mathematical equations above, consider the following:
A gas cylinder was measured to have different volumes at different temperatures as shown in Table 8. Complete the table with the necessary information.
Table 8. Data on Gas Cylinder Volumes
| Temperature (K) | Volume (m³) |
|---|---|
| 293 | |
| 303 | |
| 313 | |
| 323 | |
| 333 |
Completing the Table
To complete the table, we need to use the mathematical equation that describes Charles' Law. We can rearrange the equation to solve for V2:
V2 = V1 * (T2 / T1)
We can use the data from the table to calculate the volume at each temperature.
| Temperature (K) | Volume (m³) | V1 (m³) | T1 (K) | T2 (K) | V2 (m³) |
|---|---|---|---|---|---|
| 293 | 293 | 303 | |||
| 303 | 303 | 313 | |||
| 313 | 313 | 323 | |||
| 323 | 323 | 333 | |||
| 333 | 333 |
Calculating the Volumes
We can now use the data from the table to calculate the volume at each temperature.
| Temperature (K) | Volume (m³) | V1 (m³) | T1 (K) | T2 (K) | V2 (m³) |
|---|---|---|---|---|---|
| 293 | 0.5 | 293 | 303 | 0.52 | |
| 303 | 0.52 | 303 | 313 | 0.55 | |
| 313 | 0.55 | 313 | 323 | 0.58 | |
| 323 | 0.58 | 323 | 333 | 0.61 | |
| 333 | 0.61 | 333 | 0.64 |
Discussion
The data in the table shows that the volume of the gas increases as the temperature increases. This is consistent with Charles' Law, which states that the volume of a gas is directly proportional to its temperature in Kelvin.
The calculated volumes in the table show that the volume of the gas increases by approximately 0.02 m³ for every 10 K increase in temperature. This is a significant increase, and it highlights the importance of considering temperature when working with gases.
Conclusion
In conclusion, Charles' Law is a fundamental principle in chemistry that describes the relationship between the volume and temperature of a gas. The mathematical equation that describes Charles' Law can be used to calculate the volume of a gas at different temperatures. The real-world application of Charles' Law is essential in various fields, including chemistry, physics, and engineering.
