"In the first tutorial, we looked at how to solve for the entropy of mixing for a regular solution, and then we looked at how a highly ordered system with and uneven distribution of two species tends ...

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 ...

A solution was made by dissolving a spatula of potassium nitrate into 50 cm 3 of water. The temperature changed from 20.4˚C to 18.7˚C. Calculate the enthalpy change for this reaction. To calculate the ...

In combustion reactions, some substances will release more energy than others. Enthalpies of combustion can be used to compare which fuels or substances release the most energy when they are burned.
