Answer 1

Answer #1

0.650 Kg of water = 650 gm water = 650 /18 = 36.11 mole.

change in energy = m1 * s1 * dT1 (from 125 oC to 100 oC) + m1 * Lv (for latent heat) + m1 * s2 * dT2 (from 100 oC to 32.0 oC)

change in energy = 36.11 * 33.6 *( 125 - 100) + 36.11 * (40.67*1000) + 36.11 * 75.3 * (100 - 32)

change in energy = 30332.4 + 1468593.7 + 184897.6

change in energy = 1683823.7 J = 1683.8 KJ
