Enthalpy Diagram. It is described by the letter h in chemistry. A typical chart covers a pressure range of 0 01 1000 bar and temperatures up to 800 degrees celsius.

Hi everyone and welcome back to asfc chemistry click the little i to the top right hand corner of this video to be taken to some of our other a level chemist. Thank you for reading enthalpy diagram. What you need to know.
An enthalpy entropy chart also known as the h s chart or mollier diagram plots the total heat against entropy describing the enthalpy of a thermodynamic system.
A pressure enthalpy diagram provides this information but can be cryptic to decipher. It gives the melting curve and saturated liquid and vapor values together with isobars and isenthalps. The following diagrams are the examples of enthalpy. The overall enthalpy of the reaction is negative i e it s an exothermic reaction where energy is released in the form of heat.
