Document Summary

Change in internal energy ( u) is measured at constant v (volume) Change in enthalpy ( h) is measured at constant p (pressure). [ h = u + p v] State functions such as h and u are path independent. Hess"s law : if you can add two or more reactions together to create a new reaction, then you can add their enthalpy changes ( h) together to get the dh of the new reaction. Of a substance is formed from its. Is light a particle or a wave? . Yes, light is a particle (photon) or a wave (electromagnetic wave). It is our descriptions of light that are inadequate and incomplete. these different ways. But we can describe how light behaves. C is speed of light in a vacuum and is a constant: c . If one increases, the other decreases. and have an inverse relationship: . Do the units balance? (meters) (s -1 ) .
