## Which is clapeyron Clausius equation?

The Clapeyron-Clausius equation is a differential equation giving the interdependence of the pressure and temperature along the phase equilibrium curve of a pure substance. This equation was suggested by B. Clapeyron in 1834 and improved by R. Clausius in 1850.

## What does Clapeyron equation describe?

Equation (2.165), which is referred to as the Clapeyron equation, describes a general relationship among the pressure, temperature, volume change, and enthalpy change for a single-component, two-phase system at equilibrium.

What is Clausius-Clapeyron law?

The Clausius Clapeyron equation calculates the rate of increase in vapour pressure per unit increase in temperature. Let T be the temperature and p be the saturation vapour pressure. The Clausius Clapeyron equation for liquid-vapour equilibrium is then used. dpdT=L(T(Vv−Vl))

When can Clausius-Clapeyron be used?

The equation describes the phase transition between two phases of matter that have the same composition. Thus, the Clausius-Clapeyron equation can be used to estimate vapor pressure as a function of temperature or to find the heat of the phase transition from the vapor pressures at two temperatures.

### Why is Clausius-Clapeyron equation important?

Equation 23.4. 27 is known as the Clausius-Clapeyron Equation and allows us to estimate the vapor pressure at another temperature, if the vapor pressure is known at some temperature, and if the enthalpy of vaporization is known.

### What is the Clausius-Clapeyron relation and why is it important for climate?

The Clausius-Clapeyron relationship predicts an increase in the water holding capacity of air (the saturation water vapor pressure) of approximately 7% per degree Celsius rise in temperature2.

What is Clausius-Clapeyron’s equation of latent heat?

The left hand side is the rate of increase of vapour pressure with temperature, while S2 − S1 is equal to L/T, where L is the specific latent heat of vaporization. Thus we arrive at the Clausius-Clapeyron equation: dPdT=LT(V2−VL).
