Question

What property of water allows water striders to skate across the surface?

capillary action
specific heat
surface tension
polarity

specific heat is correct right?

Answer 1

Hey dude i know this isnt an answer, but how does the "answered" bot work? is it for 6th grade +? im just wondering cause i need help and no one has been answering my questions yet.

Answer 2

Surface tension is the property of a liquid that allows it to resist external forces, such as gravity or pressure, and form a cohesive surface layer. This cohesive layer creates a "skin" on the surface of the water, which water striders can use to distribute their weight and move across the surface without breaking it.

While capillary action, specific heat, and polarity are also important properties of water, they are not directly responsible for the ability of water striders to skate on the surface. Capillary action describes how water molecules can move through narrow spaces due to adhesive and cohesive forces, specific heat refers to the amount of heat required to raise the temperature of a substance, and polarity refers to the uneven distribution of electrons in a molecule that creates a positive and negative end.

Therefore, of the four choices given, surface tension is the best answer to the question of which property of water allows water striders to skate across the surface.
