One kilogram of water ( 1003 cm kg') in a piston/cylinder device at 298.15 k (25°c) and 1 bar is compressed in a mechanically reversible, isothermal process to 1500 bar. determine q. w, δυ, δη, and as given that β-250x106 kl and k-45x106 bar 2. liquid water at 298.15 k (25°c) and i bar fills a rigid vessel. if heat is added to the water until its temperature reaches 323.15 k (50°c), what pressure is developed? the average value of b between 298.15 to 323.15 k (25 and 50°c) is 36.2x10 k. the value of k at l bar and 323.15 k (50°c) is 4.42 x10* bar and may be assumed independent of p. the specific volume of liquid water at 298.15 k (25°c) is l.00 30 c㎡ gl
