Gibbs Free Energy

The spontaneity of a reaction cannot be decided by the enthalpy and entropy only, so a new thermodynamic function is introduced. Do you know what? It is free...

Sign Conventions and Work Done in Thermodynamics

In the field of thermodynamics, either heat is given to a system or by the system. Similarly, work may be done by the system or on the system. Let's learn more!
