//INPUT
N=1;//number of moles of carbon dioxide in kmol
T1=298;//initial temperature in K
T2=600;//final raised temperature in K
a=45.369;//coefficient in the specific heat capacity expression where Cp=a+bT+eT^-2
b=8.688*10^-3;//coefficient in the specific heat capacity expression where Cp=a+bT+eT^-2
e=-9.619*10^5;//coefficient in the specific heat capacity expression where Cp=a+bT+eT^-2
//Where Cp is in J/molK
//CALCULATION
Q=N*10^3*((a*(T2-T1)+((b/2)*(T2^2-T1^2))-(e*((1/T2)-(1/T1)))))*10^-6;//calculation of the amount of energy to be transferred in MJ using Eq.(4.25)
//OUTPUT
mprintf('\n The amount of energy to be transferred as heat= %0.3f MJ\n',Q);
