WebUsing the equation for a change in temperature and the value for water from Table 1, we find that Q = mLf = (1.0 kg) (334 kJ/kg) = 334 kJ is the energy to melt a kilogram of ice. This is a lot of energy as it represents … WebLet's guess that the final temperature would be 70 °C. Then, we'd have: x 2 ′ = 1 − 0.00102 5.0395 ≈ 19.8 % This gives: u 2 ′ = 293.03 + 19.8 % ⋅ 2468.9 = 782.4 k J k g This is more than our real u 2, but no too much. We overshot a bit, but we're close! Let's check if it isn't 65 °C instead (calculations suppressed):

WebBonus Example #1: 100.0 mL of water were initially at a temperature of 60.1 °C. After adding ice, the final temperature was 1.9 °C and the final volume 171.0 mL. Calculate the molar enthalpy of fusion for ice. Solution: 1) The warm water has given up some energy. Let us calculate that amount: q = (100 g) (58.2 °C) (4.184 J g¯ 1 °C¯ 1) q ... Webt1 = final temperature (oC, oF) t0 = initial temperature (oC, oF) The density of a fluid when temperature changes can be expressed as ρ1 = m / V0 (1 + β (t1 - t0)) = ρ0 / (1 + β (t1 - t0)) (3) where ρ1 = final density … def of trial in the bible
