To determine Energy change associated with movement of water molecules. Explanation Write the equation for energy change Δ U = − p E ( cos θ f − cos θ i ) (I) Here p is the dipole moment, E is the electric field, θ f is the final orientation angle of the water molecule and θ i is the initial orientation angle of the water molecule. Conclusion: Substitute 6.17 × 10 − 30 C ⋅ m for p , 2.95 kN / C for E , 180 ° for θ f and 0 ° for θ i in (I) Δ U = − ( 6.17 × 10 − 30 C ⋅ m ) ( 2
