Stearic Acid Cooling Curve Explanation

Stearic Acid Cooling Curve Explanation Mar 23 2023 nbsp 0183 32 In this experiment we have produced a cooling curve of stearic acid using a water bath set to 80 degrees Celsius and a 250 ml beaker The cooling curve provides information about the cooling behaviour melting point purity and crystalline structure of the stearic acid

Explain the diagonal parts of the cooling curve in terms of changes in kinetic and potential energy Do the same for the horizontal portions of the cooling curve The cooling curve for stearic acid or any substance is a graphical representation of how the temperature of the substance changes over time as it cools It is used to study the phase transitions of the substance such as from liquid to solid
