Fluorescence: Fluorescence studies prone to self
... Fluorescence by a protein is complex when there is more than one aromatic side chain. The proximity of aromatic groups in a folded protein results in efficient energy transfer between these groups. Light absorbed by one chromophore is transferred to another that absorbs at a longer wavelength, which ...

The Structure of Magnets
... Energy was defined as the ability to do work. If an object begins moving, then work is being done on it, and therefore, some form of energy is being used. We refer back to this idea to demonstrate some of the many forms that energy can take. It is suggested that a list of energy forms be generated b ...

... with higher heat to an object with lower heat. Also, the Law of Conservation of Energy tells us that the amount of heat lost by the hot object must be equal to the amount of heat gained by the cold object. As heat lost is a negative number, we will need to add a negative sign to the lost heat number ...

The problem is that we can only measure CHANGES in the Enthalpy of the system, and have no way to determine the ABSOLUTE Enthalpy. We have to define a convenient ZERO of Enthalpy for all the chemical c ...

... Both say the same thing, so both are equivalent. Both are untrue. Explanation: This is a cause-and-effect question. The color black doesn’t draw in and absorb energy. It’s the other way around—any object that does draw in and absorb energy, will, by consequence, be black in color. ...
