the following questions concerning energy released or absorbed

Answer the following questions concerning energy released or absorbed during the heating or cooling of water. a. Determine how much heat (kJ) is released upon the freezing of 2.5 x 103L of water at 0oC (assume the density of water is 1.00 g/mL).b. How much heat (kJ) would be absorbed if the same sample of water (2.5 x 103 L) initially at 0oC is melted at 0oC, warmed to 100oC, and then vaporized to steam at 100oC? (for warming: the specific heat capacity of water is 4.184J/g•oC; see Ch.3, pg 75-76) (add the heat absorbed for the three steps)c. Calculate the heat (kJ) released when this sample of steam (2.5 x 103L) condensed at 100oC into water.d. Calculate the heat (kJ) released when this sample of water at 100oC (2.5 x103L) is cooled to body temperature of 37oC. (specific heat capacity of water is 4.184 J/g•oC)
