QUESTION 5 (10 blanks) If the gravitational potential energy of the water is equal to the increase in the internal energy of the water, compute the change in its temperature (in Kelvin), if water drops from a height of 50 m. Assume no work is done on/by the water (C = 4184 J/kg K) Sol. Using the first law of thermodynamics: A U=Q - Since W = Then A U=Q But, by virtue of the problem, the internal energy is equal to AU = While Q = ΔΤ Then h= ΔΤ AT = K (2 decimal place)
