Question

If the specific heat capacity of water initially is 4.2 X 10^3 per kg per K and g=10m/s, the difference in temperature of water between the top and bottom of a 210m high water fall is___________

Answer 1

If the specific heat capacity of water initially is 4.2 X 10³ K/kg and g=10m/s, the difference in temperature of water between the top and bottom of a 210m high water fall is 0 K, cause the gravity force transforms potential energy of water into kinetic energy but not into the internal heat energy.
