How to Determine Boiling Points with Pressure

Calculating boiling point based on pressure can be done using several different formulas These formulas vary in complexity and accuracy In general units in these calculations will be in the metric or System International (SI) system resulting in temperatures in degrees Celsius (o C) To convert to Fahrenheit (o F) use the conversion T(F) = T(C) 95 + 32 where T means temperature

Heat of Fusion Example Problem

Heat of fusion is the amount of heat energy required to change the state of matter of a substance from a solid to a liquid It's also known as enthalpy of fusion Its units are usually Joules per gram (J/g) or calories per gram (cal/g) This example problem demonstrates how to calculate the amount of energy required to melt a sample of water ice

Melting Point Freezing Point Boiling Point

Melting Point and Freezing Point Pure crystalline solids have a characteristic melting point the temperature at which the solid melts to become a liquid The transition between the solid and the liquid is so sharp for small samples of a pure substance that melting points can be measured to 0 1 o C The melting point of solid oxygen for example is -218 4 o C
