Would You Expect the Surface Tension of Water to Increase

question 114

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.
