Question

Conclusions 1. How does the surface tension of water change as the temperature increase? Explanation le 2. What did you determine you tested? was the relationship between surface tension and the polarity of the liquids Explanation 3. What effect did adding soap to the water have on the surface tension of the water? Explanation: 4. What might be the environmental consequences if a significant amount of surfactant were to get into a pond? Describe any variables in your experiments that you were unable to control your results. How might you control these variables the next time you performed thi and may have affected s experiment. 5. 15

Explanation / Answer

1) When the temperature increase the viscosity decreases

because When the temperature increases, the molecules become excited and begin to move more freely.

These movements results in a energy which is enough to overcome the forces that bind the molecules together,

So this allows the liquid to become more fluid

As a result the viscosity decreases.

2)

similarly

when the temperature of a liquid increases, its surface tension decreases.

To put it simply

Surface Tension and viscosity are the result of cohesive forces among the molecules.

As the temperature increases , the number of molecules with sufficient kinetic energy to overcome the forces increases

so the surface tension and visocity decreases with increase in temperature

3)

substances with high surface tensions also tend to have high viscosities?

because

both of them are related to the cohesive forces between the molecules

higher surface tension means higher cohesive forces between the molecules which in turn means higher viscosity
