It is not true; evaporation occur at the surface of a liquid and the temperature is under the boiling point.
false
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.
True. The temperature at which a liquid turns into a gas is called the boiling point.
The arsenic has not a true boiling point; arsenic sublimes at 614 0C.
The boiling point is lower at high altitude.
100>9877

No, the boiling point of a substance varies with altitude. As altitude increases, atmospheric pressure decreases, causing the boiling point to decrease as well.
Yes, a pressure cooker raises the boiling point of water by increasing the internal pressure. This allows food to cook faster and at higher temperatures, which can help to tenderize tough cuts of meat and reduce cooking times.
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.
