M Common Ethical D. O THERMOCHEMISTRY Understanding the definitions of heat and work A mixture of gaseous reactants is put into a cylinder, where a chemical reaction turns them into gaseous products. The cylinder has a piston that moves in or out, as necessary, to keep a constant pressure on the mixture of 1 atm. The cylinder is also submerged in a large insulated water bath. (See sketch at right.) From previous experiments, this chemical reaction is known to release 133. kJ of energy. The position of the piston is monitored, and it is determined from this data that the piston does 116. kJ of work on the system during the reaction. O exothermic Is the reaction exothermic or endothermic?…

Reading List Question 15.c of 30 Submit How does the quantization of energy explain the observed photoelectric effect and emission of UV energy? When light shines on a metal, electrons can be ejected from the surface of the metal in “the photoelectric effect". Experiments showed that the wavelength of light is inversely proportional to kinetic energy of the electrons ejected. Identify the best explanation of the photoelectric effect. A) Increasing the brightness of incoming light increases the kinetic energy of the ejected electrons. B) Increasing the wavelength of incoming light increases the kinetic energy of the ejected electrons. C) Increasing the frequency of incoming light increases the kinetic energy of…
