Water falls from a height of 200 m into a pool. Calculate the rise in temperature of the water assuming no heat dissipation from the water in the pool. ( . Take g=10 ~m / s ^2 , specific heat of water .=4200 ~J /( kg K ) )

Options

  1. A0.23 K
  2. B0.36 K
  3. C0.14 K
  4. D0.48 K

Correct answer

D. 0.48 K

Step-by-step solution

aligned & mgh = ms T & T = gh s = 10 200 4200 ~K = 10 21 ~K aligned
