How does the meniscus angle change with temperature, type of liquid (eg various alkanes), density? |

Answer» f contact decrease with the addition of IMPURITIES whereas it increases if the temperature is increasedFor the explanation of why it increases with increase in temperature, I found out that the surface tension causes the increase in cohesive forces and hence a upward CONCAVE. So when temperature rises, surface tension decreases and ANGLE of contact increases.Is this explanation correct, and COULD you explain it in some other WAY or elaborate about it?And I was not able to find why does it decrease with increase in impurities |
