How do you know what has a higher boiling point?
Explanation: Boiling point is highly dependent on the intermolecular forces of a compound. Compounds with stronger intermolecular forces, larger masses, and less branching will have higher boiling points.
How do you know which solution has the highest boiling point?
Multiply the original molality (m) of the solution by the number of particles formed when the solution dissolves. This will give you the total concentration of particles dissolved. Compare these values. The higher total concentration will result in a higher boiling point and a lower freezing point.
How do you determine the highest melting point?
In general, the greater the charge, the greater the electrostatic attraction, the stronger the ionic bond, the higher the melting point.
Which solution will have the highest boiling point quizlet?
NaCl has the greatest product, so it will have the largest T and the highest boiling point.
Which 0.1 M solution has the highest boiling point?
A solution of which of the following compounds has the highest boiling point? Answer: D. 0.1 m NaCl – boiling point 1413oC.

How do you determine the highest and lowest boiling point?
3 Trends That Affect Boiling Points
- The relative strength of the four intermolecular forces is: Ionic > Hydrogen bonding > dipole dipole > Van der Waals dispersion forces. …
- Boiling points increase as the number of carbons is increased.
- Branching decreases boiling point.
What is considered high melting point?
One states a metal must have a melting point above 2200 °C, whilst the other states all metals with a melting point above 1850 °C are considered refractory metals.
|Titanium (Ti)||1668 °C||Alloying, aircraft, ships, propellor shafts, heat exchangers|
Which likely has the highest melting point?
The chemical element with the lowest melting point is Helium and the element with the highest melting point is Carbon. The unity used for the melting point is Celsius (C). Click here: to convert Celsius to Fahrenheit or Kelvin.
What does it mean to have a higher boiling point?
Boiling point is the temperature at which the vapor pressure of a chemical equals atmospheric pressure. To simply put, it measures the temperature at which a chemical boils. Similar to melting point, a higher boiling point indicates greater inter-molecular forces and therefore less vapour pressure.
