One mole of an ideal gas is heated from 100 C to 322.4 C at constant VOLUME. Report the heat added (in kJ and three significant digits) to this gas to achieve this heating. The heat capacity (Cp) is a function of temperature of the form 0.1 + 0.0002T where T is temperature in degrees Celcius and the heat capacity is in kJ/mol/C.
Stellar nuclear fusion begins with 1H and ends with 56Fe. Younger stars fuse hydrogen to form 4He, while older, more massive stars fuse helium to form heavier elements.
