1. Each vibrational mode will contribute R to the total molar heat capacity, however. 2. V the molar heat capacity at constant volume. 3. Carbon dioxide is therefore more effective than nitrogen due to its higher molar heat capacity 4. A modern version is that the molar heat capacity of a solid is " 3R" 5. This gives many solids about twice the atom-molar heat capacity at room temperature of monatomic gases. 6. Several explanations of equipartition's failure to account for molar heat capacities were proposed . quantum theory among physicists. 7. "' Molar heat capacity "'of four substances in their designated states at 1 atm pressure. 8. On an order of magnitude level, what would the molar heat capacity ( per mol of some particle ) be? 9. Molar heat of formation of ?-MoTe 2 is " 6 kJ / mol from ?-MoTe 2.10. On a per mole basis, the expression for difference in molar heat capacities becomes simply R for ideal gases as follows:
