Which of the following is an example of a gas-liquid mixture?

a. the air we breathe

c. a helium balloon

b. a carbonated drink

d. ice cubes

Option (b) is the correct answer.

Explanation:

A carbonated drink is defined as a drink in which carbon dioxide gas is dissolved into a liquid.

For example, in cold drinks like pepsi, coca-cola etc carbon dioxide gas is present into the liquid.

The air we breath contains a mixture of gases like nitrogen, oxygen, etc.

Ice cubes are the solid state of water and there is no presence of gas in an ice cube.

A helium balloon also contains only helium gas and no other gases.

Therefore, we can conclude that out of the given options a carbonated drink  is an example of a gas-liquid mixture.

vanderwaal's forces of attraction are the electrostatic intermolecular forces that exist in a molecule due to the temporary or permanent dipoles that are developed in a molecule. in , the major intermolecular forces are dipole-dipole interactions as the molecule is polar (bent structure). so the vanderwaal's forces of interaction in between molecules are the permanent dipole-dipole interactions that develop due to the dipole that exists in between the polar h - s bond. the positively charged hydrogen atom is attracted towards the negative end of the dipole that is sulfur of the adjacent molecule. therefore, these forces of attraction are relatively stronger than that of london dispersion forces that exist in non polar molecules.
