10 Questions
What are dipole-dipole forces?
Attractive forces between the positive pole of one polar molecule and the negative pole of another polar molecule
What is the process called when the positive pole of one molecule attracts the negative pole of another molecule?
Dipole-dipole interaction
What determines the strength of dipole-dipole forces?
Electronegativity difference between the bonded atoms and distance between the molecules
In which state of matter are dipole-dipole forces weaker?
Gases
In what type of molecules do dipole-dipole forces exist?
Polar molecules
What is the definition of vapour pressure?
The pressure exerted by vapours in equilibrium with its liquid at a particular temperature
What causes the establishment of dynamic equilibrium in vapour pressure?
Equal rates of evaporation and condensation
What is the role of kinetic energy in the formation of vapour pressure?
Molecules with greater kinetic energy escape the liquid surface and form vapours
What does vapour pressure measure?
The tendency of a liquid to evaporate
How is vapour pressure affected by temperature?
Vapour pressure increases with increasing temperature
