It is not true; evaporation occur at the surface of a liquid and the temperature is under the boiling point.
The melting point is the temperature at which a solid turns into a liquid, while the boiling point is the temperature at which a liquid turns into a gas. Both melting and boiling points are physical properties that are specific to each substance and can be used to identify and characterize materials.
True. The addition of a nonvolatile solute to a solvent increases the boiling point of the solution compared to the pure solvent. This is known as boiling point elevation, and it occurs due to the decrease in vapor pressure of the solution.
No, because they get gas above them but if you stick your finger in it it will be liquid.
The arsenic has not a true boiling point; arsenic sublimes at 614 0C.
True. The temperature at which a liquid turns into a gas is called the boiling point.
The boiling point is lower at high altitude.

No, the boiling point decrease at high altitudes.
The boiling point of 2 m KF in water is 102.4ºC. The boiling point of a 0.5 m aqueous solution of LiOH is the same as the boiling point of a 0.5 m aqueous solution of LiCl.
Yes, it is true.
No. Atmospheric pressure falls the higher you go. The boiling point of a liquid varies with ambient pressure. If the pressure is lower then the boiling point will be lower.
Yes Since they have a lower boiling point, they have a higher vapor pressure - or to be more exact, a higher fugacity, than the higher boiling point components at the same temperature.
