The normal boiling point of liquid methanol is 338 K. Assuming that its molar heat of vaporization is constant at 38.8 kJ/mol, the boiling point of CH3OH when the external pressure is 0.730 atm is

the molecules move in straight line until they collide with each other or with the walls of the container. collisions are perfectly elastic; when two molecules collide, they change their directions and kinetic energies, but the total kinetic energy is conserved.

explanation:

the positions which points up in upward carbon and down in downward carbon are axial

and vice versa holds true for equatorial positions

so the correct answer with labelled diagram will be
