In this worksheet, we will practice using contact angles to calculate and compare the surface tensions of water–solid interfaces.
How does evaporation of a dilute aqueous alcohol solution at affect the alcohol concentration and meniscus curvature?
- AMeniscus curvature decreases and alcohol concentration increases.
- BBoth quantities remain constant.
- CBoth quantities increase.
- DMeniscus curvature increases and alcohol concentration decreases.
- EBoth quantities decrease.
