Enthalpy; Definition, Importance And Applications: Enthalpy is the measurement of energy in a thermodynamic system. It is a fundamental concept in thermodynamics. It represents the total energy ...

Enthalpy? A Fancy Word for Heat! This program presents the important concepts of pressure enthalpy in a manner that will appeal to the service technician. Each refrigerant has its own properties and ...

The pressure-enthalpy (P-H) diagram is a useful tool for refrigeration engineers and designers. It is also useful for service technicians. The P-H diagram is a graphical representation of the ...

The path (1- 2s) is for an ideal isentropic compressor, the path (1 - 2) is for a real compressor. The path (2 - 3) takes place in the condensing tank, and the path (4 - 1) is in the evaporating tank.

Since their discovery at Drexel University in 2011, MXenes — a family of nanomaterials with unique properties of durability, conductivity and filtration, among many others — has become the largest ...

Hess’s Law states that the enthalpy change for a chemical reaction is independent of the route taken. This means that the enthalpy change for the overall process will be identical regardless of how ...

Energy is required to break a covalent bond between two atoms to overcome the attractive force. Bond breaking is an endothermic process. The opposite is true if we want to make new bonds. Energy is ...

The fuel cell thermodynamic efficiency is given by the ratio of the Gibbs function change to the Enthalpy change in the overall cell reaction. The Gibbs function change measures the electrical work ...
