Liquid water at 200 kpa and 15°c is heated in a chamber by mixing it with superheated steam at 200 kpa and 150°c. liquid water enters the mixing chamber at a rate of 4.3 kg/s, and the chamber is estimated to lose heat to the surrounding air at 20°c at a rate of 1200 kj/min. if the mixture leaves the mixing chamber at 200 kpa and 80°c, determine (a) the mass flow rate of the superheated steam and (b) the rate of entropy generation during this mixing process.

i can ! i just need to know what the paragraph is! : p

the best answer is d because the strong cohesion is caused by the ability of water molecules to undergo hydrogen bonding.

a is incorrect because when water solidifies, it becomes   ice, which expands and occupies a bigger volume for the same mass of water in its liquid state.

b is incorrect because water has high surface tension. besides bonding to itself it hydrogen bonds to other molecules at the top decreasing possibility for breaking of attractive forces.

c is incorrect because the water molecule has oxygen which is highly electronegative and so pulls the electron pair towards itself creating a dipole moment, making the molecule polar.

e is incorrect because water has strong adhesion, ability to stick to other molecules such as glass because of this molecules having stronger hydrogen bonding than water.

catya that's not even a b or c
