... "All elements in their standard states (oxygen gas, solid carbon in the form of graphite, etc.) have a standard enthalpy of formation of zero, as there is no change involved in their formation." The problem is that we can only measure CHANGES in the Enthalpy of the system, and have no way to determi ...

Particle Physics and Cosmology
... Why do particle physicists care about cosmology? Cosmology poses fundamental questions: – What is dark matter? – What is dark energy? – Why is there more matter than anti-matter? The standard model of particle physics is amazingly successful, but… It’s missing 96% of the universe, and we don’t under ...

In fact, air resistance is negligible for many practical purposes, so our calculations here won't be too unrealistic. If an object falls a certain distance, work will be done on it by the gravi ...
