According to debye's lock the molar heat capacity at constant volume of a diamond wheres with the temperature as follows Cv = 3R 4π⁴/5 (T/ theta d)³ what is the entropy change in units of R of a diamond of 1.2g mass when it is heated at constant volume from 10 to 350K? The molar mass of diamond is 12h and theta d is 2230K
