19. determine the final state and its temperature when 150.0 kj of heat are added to 50.0 g of water at 20 ºc. (specific heat of water = 4.184 j/g ºc; specific heat of steam = 1.99 j/g • ºc; ∆hfus (h2o) = 6.01 kj/mol; ∆hvap (h2o) = 40.79 kj/mol). (5 points)

The amount of energy to reach the boiling point is . To pass the boiling point, are necessary (18.02 is the molar mass of water). This means that are left. This allows the steam to heat another . Therefore, it ends as steam at temperature

a person with a mass of 106kg has a weight of 1060n

real, smaller and upside-down.   so the answer should be b.
