[单选题]
The image shows a water kpuw4 wb5xx m4y m.8n - znuj/so3u-h0strider (G. lacustris) on the sur 0c.8 eg.:htn dhyn /llface of a pond. What property o hlc: n l80edny. gh/t.f water is not depicted in the image?
A. Adhesion
B. Exertion of buoyant forces
C. Cohesion
D. Thermal conductivity
参考答案: D
本题详细解析:
Thermal conductivity refers o0 q8 e 9l,82qmzx7qfyyi1qg :cwcw.s to a material's ability to conduct heat. While water does have a relatively high thermal conductivity compared to other liquids, thi s8q1 ,x9 z78y2e:f.g0 iwlqqqcowmcys property is not directly related to the ability of the water strider to stay on the surface of the water. The image does not depict thermal conductivity, so Choice D is correct.Choice A is incorrect as adhesion is the ability of water to form hydrogen bonds with other polar molecules. The ability of the water strider to stay on the surface of the water is due to surface tension and adhesion between the water molecules and its legs. Choice B is incorrect as the water strider can stay on the water surface due to the exertion of buoyant forces, which counteract its weight. Choice C is incorrect as cohesion is the ability of water molecules to stick to each other, which creates the surface tension that allows the water strider to rest on top of the water.
