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.

Calculate the ratio of h+ ions to oh– ions at a ph = 6. find the concentration of h+ ions to oh– ions listed in table b of your student guide. then divide the h+ concentration by the oh– concentration. record this calculated ratio in table a of your student guide. compare your approximated and calculated ratios of h+ ions to oh– ions at a ph = 6. are they the same? why or why not? record your explanation in table a. what is the concentration of h+ ions at a ph = 6? mol/l what is the concentration of oh– ions at a ph = 6? mol/l what is the ratio of h+ ions to oh– ions at a ph = 6? : 1
