A balloon filled with helium gas occupies 2.50 L at 25 degrees celcius and 1.00 atm. When released, it rises to an atlitude where the temperature is 18 degrees celcius and the pressure is only 0.80 atm. Calculate the new volume of the balloon.
One way to measure ionization energies is ultraviolet photoelectron spectroscopy (UPS, or just PES), a technique based on the photoelectric effect. In PES, monochromatic light is directed onto a sample, causing electrons to be emitted.
