Question

Select the claim that correctly describes the surface tension of water and the ability of the water strider to walk on water if the pond temperature increases due to global warming.

A
Global warming would increase the surface tension of water, making it easier for water striders to walk on water.

B
Global warming would increase the surface tension of water, making it harder for water striders to walk on water.

C
Global warming would decrease the surface tension of water, making it easier for water striders to walk on water.

D
Global warming would decrease the surface tension of water, making it harder for water striders to walk on water.

Answer 1

Answer:

The correct option is;

D Global warming would decrease the surface tension of water, making it harder for water striders to walk on water

Explanation:

Global warming involves the heating of the ecosystems on Earth due to human activity, which results in rising temperatures

As the temperature of the water rises due to global warming the surface tension decreases due to the increasing ratio of the force of higher kinetic energy water molecule to inter-molecular cohesive forces pulling the water together, which tends to weaken the effect of the cohesive forces and thus reduce the surface tension

As the surface tension has been reduced, the water striders will find it difficult to walk on the water surface as the maximum weight the water surface can lift without shearing, due to surface tension is reduced.
