Why does the potato soften and egg gets harder in the same boiling water?​

Heating raw potatoes in hot water will make the starch granule swell and absorb water, becoming soft and easier to digest. Eggs contain mostly protein in liquid form. Heating protein will make it undergo denaturation process. The protein structure changes, becoming firm solid and easier to digest.

explanation:

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.
