The P1 T1 P2 T2 Calculator is a tool designed to determine the final pressure (P2) given initial pressure (P1), initial temperature (T1), and final temperature (T2) using the combined gas law formula:
Formula
The formula for calculating the final pressure (P2) is straightforward:
P2 = (P1 * T2) / T1
Utilizing this formula simplifies calculations related to gases under different temperature and pressure conditions.
Table of General Terms
| Term | Description |
|---|---|
| Initial Pressure | The starting pressure before any changes occur |
| Initial Temp | The temperature at the starting point |
| Final Temp | The temperature at the final state |
| Final Pressure | The pressure after the temperature change |
Understanding these terms can assist users in applying the calculator effectively for various scenarios without the need to perform calculations each time.
Example
Let’s consider an example where the initial pressure (P1) is 10 atm, the initial temperature (T1) is 300 K, and the final temperature (T2) is 400 K.
Using the formula: P2 = (10 * 400) / 300 P2 = 13.33 atm
