Question

 

A glass of ice water containing nine ice cubes will be colder than a similar-size glass of ice water containing only three ice cubes.

True

False

Heat is released when a liquid freezes into a solid.

True

False

All intermolecular forces are broken when a liquid vaporizes into a gas.

True

False

Dispersion forces result from the temporary distortion of the electron cloud in an atom or molecule which increases in magnitude with increasing size.

True

False

Dipole-dipole forces are weaker than dispersion forces.

True

False

Ion-dipole force is considered the weakest of the different types of intermolecular forces.

True

False

Attraction between the Na cation and Cl anion holds the solid lattice of sodium chloride together.

True

False

Answer 1

A glass of water with nine ice cubes will be colder than containing 3 ice cubes

* True

as it is obvious that as volume of glass is same more ice cubes make it colder

When any liquid freezes into a solid

* False

this is because as we have to give energy to convert liquid to soild

All intermolecular forces must be broken to form gas from liquid

* True

as otherwise they will lead to some liquid like nature

Dispersion forces arise due to temporary formation of dipole of any non polar molecule

so it is * True

Dipole dipole forces are weaker than dispersion forces

* False

Ion dipole forces are very stronger forces in different type of forces as one species involved is ions which have whole complete charge , so given statement is

* False

Yes it is true that attraction between positive cation Na+ and negative ion Cl- will hold NaCl together in crystal lattice .
