Question

The figure shows two fish tanks, each having ends of width 1 foot. Tank A is 3 feet long while tank B is 6 feet long. Both tanks are filled to the same depth. S_A = the magnitude of the force of the water on the end of tank A S_B = the magnitude of the force of the water on the end of tank B B_A = the magnitude of the force of the water on the bottom of tank A B_B = the magnitude of the force of the water on the bottom of tank B Using the notation given above, which one of the following sets of equations below is correct for this situation? S_A - S_B and B_A = B_B S_A = 2S_B and B_A = B_B 2S_A = S_B and 2B_A = B_B S_A = S_B and 2B_A = B_B S_A = 2S_B and B_A = 2B_B What is the latent heal of vaporization of this material. 50 kcal/kg 100 kcal/kg 150 kcal/kg 300 kcal/kg 450 kcal/kg

Explanation / Answer

5.

here form the figure is it clear that the answer is option D

6.

Answer C 150kcal/kg

see the horizontal line at 150C, 300 to 450cal

so heat added during the vapourization is 450 - 300 = 150 Kcal/Kg
