Answer

Answer:

Water striders use London dispersion forces to walk on water.

Explanation:

Step1: Analyze gecko - adhesion

Geckos stick to surfaces through van der Waals forces (including London - dispersion forces), not covalent bonds. Covalent bonds are intramolecular, not for surface - adhesion in this context.

Step2: Compare force strengths

There is no general truth that the force water striders use is stronger than geckos'. Both use van der Waals - type forces for their respective functions.

Step3: Understand water - strider force

Water striders can walk on water due to the surface tension of water, which is related to the London dispersion forces between water molecules and the non - polar nature of their legs that interact with water via these weak intermolecular forces.

Step4: Analyze force nature

Both geckos and water striders use attractive forces. Geckos stick to surfaces and water striders interact with water surface through attractive intermolecular forces.
