The molar heat capacity at constant volume of a metal at low temperatures varies with the temperature according to the equationCV/n = (124.8/?)3 T3 + γT,
where Θ is the Debye temperature, ϒ,is a constant, and Cv/n is measured in units of mJ jmol· K. The first term on the left is the contribution attributable to lattice vibrations and the second term is due to the contribution of free electrons. For copper, Θ is 343 K and, is 0.688 m.l/mol K2. How much heat per mole is transferred during a process in which the temperature changes from 2 to 3 K?

Consider an infrared grating with 84.0 lines per mm and 15.0 mm of illuminated area. calculate the first-order resolution (λ/Δλ) of this grating. How far apart in cm^-1 must two lines centered at 1200 cm^-1 be if they are to be resolved.
One of the key steps in brewing beer (or brewing root beer, if you prefer) is conversion of starch stored the barley into di- and trisaccharides through a process called "mashing" of the grain
