When 1 mole of ice melts at 0°C and constant pressure of 1 atmosphere, 6025 J of heat is absorbed by the system. The molar volume of ice and water are 0.020 and 0.018 dm³, respectively. Calculate ΔE. (1 dm³·atm = 101.33 J) (KMU MDCAT 2024)

Verified Answer & Explanation⌄

Correct Answer: D) 6025.20 J

Concept Explanation

At constant pressure, ΔH = ΔE + PΔV. Here ΔV = 0.018 − 0.020 = −0.002 dm³, so ΔE = 6025 − PΔV ≈ 6025.20 J.
