I'm not sure this answers why, but I'll try. As water dissolves matter, the solution's vapor pressure lowers. It cannot boil (evaporate) unless its vapor pressure equals that of the atmosphere. Since the vapor pressure reduces as the solution dissolves more solute (that which is dissolves), the temperature must increase to increase the vapor pressure of the solution. When the vapor pressure reaches that of the atmosphere, the solution begins to boil. Therefore, the boiling occurs at a higher temperature.

What elements have the lowest boiling and melting points?
The noble gases, such as helium and neon, have the lowest boiling and melting points among the elements. These elements are gases at room temperature and have very weak interatomic forces that require little energy to separate them into individual atoms.
How do you find highest boiling point of an element?
The highest boiling point among elements can be found by looking at the group of the periodic table in which the element is located. Generally, elements with higher atomic numbers and greater atomic masses will have higher boiling points. Within a group, elements with stronger intermolecular forces, such as metallic and covalent bonding, will also tend to have higher boiling points.
What is the boiling point of tungsten and how does it compare to other elements?
The boiling point of tungsten is 5,555 degrees Celsius, making it one of the highest boiling points of all elements. This high boiling point is due to the strong metallic bonds in tungsten, which require a lot of energy to break apart compared to other elements.
What are the boiling points of volatile compounds?
The boiling points of volatile compounds will vary depending on the specific compound. Generally, volatile compounds have low boiling points, typically below 100°C. Some examples of volatile compounds with low boiling points include ethanol (78.3°C), acetone (56°C), and diethyl ether (34.6°C).
Do all liquids have the same boiling and melting point?
No, different liquids have different boiling and melting points depending on their chemical composition. The boiling point is the temperature at which a liquid turns into a gas, while the melting point is the temperature at which a solid turns into a liquid. Each liquid has its own unique set of physical properties that determine its specific boiling and melting points.
Why elements of the same shape have different boiling points?
elements of same shape have different boiling points because their bonding may vary! the elements with covalent bonds will have high boiling point!
Do elements compounds and mixtures have fix melting and boiling point?
Elements have fixed melting and boiling points, while compounds have varying melting and boiling points depending on their composition. Mixtures do not have fixed melting and boiling points, as they are composed of multiple substances which each have their own individual melting and boiling points.
What is the boiling point of any liquids?
Boiling points vary from liquid to liquid.
What is the difference between freezing and boiling points on a Fahrenheit scale?
The difference between the freezing and boiling points vary from substance to substance.
What elements have high boiling points?
As examples are wolfram, tantalum, rhenium.
Where elements on the periodic table with the highest boiling points app?
Elements with the highest boiling points are typically found in the group of transition metals and some metalloids. For example, tungsten (W) has one of the highest boiling points at around 5,555°C. These elements often have strong metallic bonds and a dense atomic structure, which contribute to their elevated boiling points. Additionally, some heavy noble gases like radon also exhibit high boiling points, but generally, the trend is seen among the transition metals.

What are a characteristics of elements?
Several characteristic properties include melting and boiling points, density, and reactivity.
How do the boiling and freezing points between the Fahrenheit and celsius?
Boiling points and melting points differ for different elements and compounds. However, if water is considered, the freezing point is 0 degree Celsius which is 32 degree Fahrenheit. Boiling point is 100 degree Celsius which is 212 degree Fahrenheit.
What are the boiling points of volatile compounds?
The boiling points of volatile compounds will vary depending on the specific compound. Generally, volatile compounds have low boiling points, typically below 100°C. Some examples of volatile compounds with low boiling points include ethanol (78.3°C), acetone (56°C), and diethyl ether (34.6°C).
