One kg of liquid water at 25 , for which cp = 4.18 kJ kg−1−1: (a) Experiences a temperature increase of 1 K. What is ∆U, in kJ? (b) Experiences a change in elevation ∆z. The change in the potential energy ∆Ep is the same as∆U in part (a). What is ∆z, in meters? (c) Is accelerated from rest to a final velocity u. The change in the kinetic energy ∆EK is the same as ∆U in part (a). What is u in m/s?
