The amount of heat needed to raise the temperature of 1 mole of a substance by one Celsius degree (or, equivalently, one kelvin) is called the molar heat capacity of the system, denoted by the letter C. If a small amount of heat dQ is put into n moles of a substance, and the resulting change in temperature for the system is dT, then C=1ndQdT. This is the definition of molar heat capacity--the amount of heat Q added per infinitesimal...
a. Given that the energy of an ideal gas is a function of temperature only, show how the conclusion can be reached that the enthalpy of an ideal gas is also only a function of temperature. b. Show that for an ideal gas Cp-Cv=R Hint: How much more heat is required to raise the temperature of the gas by 1K if the process is carried out at constant pressure rather than constant volume? Explain.
