## How to use the Clausius-Clapeyron Calculator?

Understanding the terms used in our calculator is essential:

**Temperature (T)**- The temperature at which the substance is observed, measured in Kelvin (K).**Enthalpy of Vaporization (ΔHvap)**- The energy required to turn the substance from a liquid into a gas, given in Joules per mole (J/mol).**Pressure (P)**- The vapor pressure of the substance, provided in Pascals (Pa).

## What is the Clausius-Clapeyron equation?

The Clausius-Clapeyron equation is a pivotal concept in thermodynamics, defining the relation between the vapor pressure of a substance and its temperature. It serves as a tool to explore phase transitions and understand the behavior of substances in their gas and liquid phases.

Defined as: \dfrac{d \ln P}{dT} = \dfrac{\Delta H_{\text{vap}}}{RT^2}

The equation finds extensive applications across fields like meteorology, material science, and chemical engineering, aiding in the prediction and study of phenomena like cloud formation, properties of materials under varying temperatures, and design of processes involving phase transitions.

## Clausius-Clapeyron Calculation Formulas

To calculate using the Clausius-Clapeyron equation, the following formula is applied:

Rate of Change in Vapor Pressure:\dfrac{dP}{dT} = \dfrac{P \Delta H_{\text{vap}}}{RT^2}

**dP/dT**- Rate of change of vapor pressure with respect to temperature.**P**- Vapor Pressure.**ΔHvap**- Enthalpy of Vaporization.**R**- Universal Gas Constant.**T**- Temperature in Kelvin.
