What Is the Charles's Law Volume & Temperature Calculator?
Charles's Law was formulated by Jacques Charles in the 1780s and describes isobaric gas thermal expansion.
How Does the Charles's Law Volume & Temperature Calculator Work?
Adding thermal energy accelerates molecular speed. To maintain constant pressure against a movable boundary, the volume must expand.
Charles's Law Volume & Temperature Calculator Formula & Variables
The core mathematical equation utilized by this calculator is expressed as:
\frac{V_1}{T_1} = \frac{V_2}{T_2} \implies V_2 = V_1 \frac{T_2}{T_1}
Gas volume expands proportionally with absolute temperature in Kelvin at constant pressure.
How to Use the Charles's Law Volume & Temperature Calculator
- Select the target variable.
- Enter known volumes and temperatures in Celsius.
