Precisely 14.3 mL of water at 30.0 degrees Celsius are additional to a hot iron skillet. All of the water is rehabilitated into steam at 100 degrees Celsius. The mass of the pan is 1.25 kg also the molar heat capacity of iron is 25.19 J/(mol*degree Celsius). What is the temperature change of the skillet in degrees Celsius?
For atomic iodine, determine the degeneracy (which arises from the spin multiplicity) of the first two electronic states. Both are derived from the same S-L term symbol, using spin-orbit (J) coupling. The second state lies 7580 cm-1 above the firs..
