Would You Expect the Surface Tension of Water to Increase

Multiple Choice

Would you expect the surface tension of water to increase or decrease with temperature?

A) At warmer temperatures water molecules are moving faster. This increased friction produces a stronger electrical charge, causing them to cohere more strongly, which increases surface tension.
B) At cooler temperatures water molecules are moving slower, which makes it relatively easy for them to cohere to one another. This, in turn, increases the surface tension.
C) At warmer temperatures water molecules are moving faster, which makes it easier for them to bump into and cohere to one another, which increases surface tension.
D) At cooler temperatures, the water molecules adhere more strongly to each other because they condense as the reach freezing point, which increases surface tension.
