The molar heat capacity of a certain substance varies with temperature according to the empirical equation
C = 29.5 j/mol .K + (8.20 X 10-3 J/mol .K2) T
How much heat is necessary to change the temperature of 3.00 mol of this substance from 27°C to 227°C? (Hint: Use Eq. (17.18) in the form dQ = nC dT and integrate.) |
