When water is boiled under a pressure of 2.00atm, the heat of vaporization is 2.20×106j/kg and the boiling point is 120∘c. at this pressure, 1.00kg of water has a volume of 1.00×10−3m3, and 1.00 kg of steam has a volume of 0.824m3.

a)compute the work done when 1.00kg of steam is formed at this temperature

b)compute the increase in internal energy of the water.

A2000 kg car is rounding a curve of radius 200 m on a level road. the maximum frictional force the road can exert on the tires of the car is 4000 n. what is the highest speed at which the car can round the curve?

Which additional product balances the reaction h2so4 + 2naoh → na2so4 + 2h2o 2oh h2o2 h3o

Click the game tab at the bottom of the simulation and select level 1. (there is no seesaw balance for this part of the activity.) balance the first equation, and click check to see if you got it right. if you can’t balance it in the first try, you can try again. work through the five equations for level 1. click continue to go on to level 2, and later level 3. each level is more difficult than the one before. keep trying until all the equations are balanced. in one or two sentences, describe how you did in the balancing game. in a few more sentences, explain one strategy you learned for balancing more complex equations.
