Water falls from a height of 84 m. Assuming that all the energy is converted into heat, the rise in temperature of water will be (4200 J/(kg °C) and g=10 m/s2)?

  1. They want you to use
    C= 4200 J/ kg*degC for the specific heat and
    g = 10 m/s^2 for the acceleration of gravity
    H = 84 m is the height
    Energy conservation tells you that
    C*(deltaT) = g*H
    Solve for deltaT, in degrees C

  3. C∆T=gH
    C of water=4200 J/kg°C
    4200(T2-T1)= 10×84
    T2-T1=10×84/4200
    T2-T1=0.2°C
