What characteristics is the boiling point of a liquid related to?
Under standard temperature and pressure, the boiling point of a liquid is most closely related to the amount of dissolved solute in the liquid and the intermolecular forces within the liquid.
What is the temperature at which a liquid becomes a gas?
Depends on which liquid but is known as the boiling point.
WHY ammonia has higher boiling point then phosphine?
NH3 exhibits hydrogen bonding in addition to dispersion forces. This significantly increases the intermolecular force, and raises the boiling point. PH3 does not exhibit hydrogen bonding and the dominant intermolecular force holding these molecules together is dispersion forces. (Dispersion forces also known as Van Der Waal Force)
What determines the boiling point of a substance?
== == The amount of force that is holding the molecules of the substance together (intermolecular forces). A lot of things factor into this, including: * Hydrogen bonding * Ionic interactions * Hydrophobic interactions * Van der Waals forces * Permanent dipole-dipole interactions The stronger the intermolecular forces are (per molecule), the higher the boiling point will be, as it will require a greater amount of heat energy to overcome the intermolecular forces that hold molecules in a liquid state.
How does temperature change during boiling?
The process that occurs during boiling of liquid is energizing of water molecules (H2O) to give them excessive energy for excitement to change their form to gas from liquid. This energy can be provided by heating and electric current. In the liquid state, atoms and molecules are bound together by strong intermolecular forces as compared to gases.While boiling a liquid we provide heat to the molecules whereby their kinetic energy is enhanced and they now have enough energy to overcome the cohesive forces and escape from the liquid surface hence changing into gas.This process is called evaporation.
How do intermolecular forces affect the boiling point of liquid?
the stronger the intermolecular force, the more energy is required to boil the liquid ...
What can be said about boiling point of a liquid?
The stronger the intermolecular forces in a liquid, the higher the boiling point. -APEX
What inter molecular force would affect the boiling point the least?
Dispersion forces would have the least effect on the boiling point of a liquid. They are the weakest intermolecular forces.
Can be said about the boiling point of a liquid?
The stronger the intermolecular forces in a liquid, the higher the boiling point. -APEX
What can be said about the boiling point of liquid?
The stronger the intermolecular forces in a liquid, the higher the boiling point. -APEX
What is the relationship between the strength of the intermolecular forces and boiling point?
Boiling can only occur when the kinetic energy of heat overcomes the intermolecular forces holding a liquid together, so the greater the intermolecular forces, the higher the boiling point.
How do intermolecular forces affect the boiling of a liquid?
The stronger the forces, the more heat that must be added to boil the liquid
What is the relationship between intermolecular forces and vaporization points?
The greater the potential of a liquid's molecules to interact with each other through intermolecular forces, the lower the vapour pressure is going to be above the liquid (because molecules will preferentially stay liquid and interact with other molecules rather than fly away as a gas), and the lower the boiling point of the liquid. Therefore the relationship is an inverse one.
What characteristics is the boiling point of a liquid related to?
Under standard temperature and pressure, the boiling point of a liquid is most closely related to the amount of dissolved solute in the liquid and the intermolecular forces within the liquid.
How can the boiling and the melting point be used to help identify substances?
intermolecular forces are hard to overcome...apex
Why do molecular solids have lower boiling points than ionic solids?
In the liquid the intermolecular forces between covalent molecules are weaker than the forces between ions.
How does the strength of liquids intermolecular forces affect its viscosity?
liquid's particles are not as close as to that of the solid the very reason why it cannot be held.because of this ability of liquid to flow, it affects the forces of a liquid to flow thoroughly.
