Question

Use the Clapeyron equation to estimate the slope of the solid-liquid phase boundary of water given that the enthalpy of fusion is ________?

Answer 1

The Clapeyron equation can be used to estimate the slope of the solid-liquid phase boundary of water.

Step-by-step explanation:

The Clapeyron equation can be used to estimate the slope of the solid-liquid phase boundary of water. The Clapeyron equation is:

dP/dT = ΔHfus / TΔV

Where dP/dT is the slope of the phase boundary, ΔHfus is the enthalpy of fusion, T is the temperature, and ΔV is the change in volume during fusion.

To estimate the slope, we need the value of ΔHfus for water. The enthalpy of fusion for water is 6.01 kJ/mol. By rearranging the equation, we can solve for the slope:

dP/dT = (6.01 kJ/mol) / TΔV

So, with the given enthalpy of fusion, we can use the Clapeyron equation to estimate the slope of the solid-liquid phase boundary of water.
