Based on the thermodynamic properties provided for water, determine the energy change when the temperature of 0.750 kg of water decreased from 115 °C to 43.0 °C.
mass of water = 0.750 kg = 750 g
moles of water = 750 / 18.02 = 41.63 mol
115o C ---------- 100 oC ----------- 43 oC
Q1 = m Cp dT
= 41.63 x 33.6 x (115 - 100)
= 20982.51 J
Q2 = n x delta Hvap
= 41.63 x 40.67
= 1693.09 kJ
Q3 = n Cp dT
= 41.63 x 75.3 x (100 - 43)
= 178680 J
total heat = Q1 + Q2 + Q3
= 1892.75 kJ
Energy change = - 1.89 x 10^3 kJ
