Enthalpy

Definition: Enthalpy is a thermodynamic property that relates to the heat content of a system at constant pressure. It is the sum of the internal energy of a system and the product of the pressure and volume.

Enthalpy is commonly represented by the symbol 'H' and is measured in joules (J) or calories (cal). It is used in various fields of science and engineering, particularly in thermodynamics and chemical reactions, to quantify the energy changes occurring during a process.

Example sentences:

1. The enthalpy of a reaction can be calculated by measuring the heat exchanged with the surroundings.
2. Increasing the temperature of a substance typically leads to a positive change in enthalpy.
3. Understanding the enthalpy of combustion is crucial in designing efficient engines.
4. Enthalpy diagrams are useful tools to visualize the energy changes during a chemical reaction.
