    transformations are that light must be absorbed by a compound in order for a photochemical reaction to take place‚ and that for each photon of light absorbed by a chemical system only one molecule is activated for subsequent reaction. This "photo equivalence law" was derived by Albert Einstein during his development of the quantum (photon) theory of light. Absorption of visible and/or ultraviolet light by a molecule transfers all the energy of the photon to one molecule. This is sufficient energy to excite

    Abstract: This report presents the reason why the ocean does not freeze in the winter. Since the ocean consists of salt water‚ an experiment was done to test the effect of freezing on salt water compared to pure water. The experiment was conducted three times in order to obtain accurate results and eliminate errors. In addition to the salt and pure water experiment‚ a variation of this experiment was created to test other options. In the variation experiment the effect of freezing on sugar water

    forms of infectious diseases. The chemotherapeutic agent works by stopping the bacteria from reproducing. There are two different kinds of chemotherapeutic agents. The first kind is an antibiotic‚ which slow down the growth of microorganisms. The second kind of chemotherapeutic agent is synthetic drugs. Synthetic drugs are artificially made in a laboratory. Chemotherapy began in the 1940s and is now a multi-billion dollar industry. Different antibiotics and synthetic drugs all have different modes
