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

the independent variable, the one that is intentionally manipulated, is whether or not the car hits the barrier.

the dependent variable, the one that you measure the response in, is the distance that the washers travel.
