At 300 k, a real gas has the following data: (p = 0.500 mpa, vm = 4.9736 dm/mol) and (p = 1.500 mpa, vm = 1.6483 dm/mol). if this real gas behaves like the van der waals gas (p = -2). determine the van der waals parameters a (in atm dm®/mol) and b (in dm®/mol). (b) (15pt) determine the value of the second virial coefficient at 600 k for the above gas based on the van der waals gas.

h let me think

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.
