Question: calculate the change in enthalpy as 1 kg of nitrogen...
Calculate the change in enthalpy as 1 Kg of nitrogen is heated
from 1000 K to 1500 K, assuming the nitrogen is an ideal gas at a
constant pressure. The temperature-dependent specific heat of
nitrogen is: Cp = 39.06 - 512.79T^-1.5 + 1072.7T^-2 - 820.4T^-3, Cp
is in kJ /kmole· K, and T is in K.
a) 600 kJ
b) 700 kJ
c) 900 kJ
d) 800 kJ
e) 1000 kJ
