Specific heat capacity is the amount of heat that is required to rise a temperature of 1 kg substance by 10C . The amount of heat is calculated by the formula, q = nC∆T Where, q represents heat n represents moles ∆T represents difference in temperatureThe calculation of heat is shown below: q = nC∆T=1×29×80-50=870J= 0.870 kJ Heat added to melt 1 mol of X = 9 kJThe calculation of heat to raise temperature to 135 0C is shown below: q= nC∆T=1×57×135-80= 3135 J= 3.135 kJ Heat added to boil 1 mol of X = 38.00 kJHeat used = 0.870 + 9 +3.135 = 13.005 kJ The calculation of heat is used to convert X(l) to X(g) is shown below: Heat = 15-13.005 = 1.995 kJThe graph is shown below:
