Questions of the day 1. What is the difference between cohesion and adhesion? 2. What are some “real-life” examples of adhesion and cohesion being used?

Adhesion Vs Cohesion Adhesion: the attraction between molecules of a different substance Cohesion: the attraction between molecules of the same substance

Capillary Action is a phenomenon where liquid spontaneously rises in a narrow space such as a thin tube, or in porous materials Why do you thing this happens?

Surface Tension is a property of the surface of a liquid that allows it to resist an external force How does cohesion/adhesion fir in with surface tension?

pH Scale

Buffers A weak acid or base that is used to change the pH of a solution in small increments Question: Solution has a pH of 12 and we need the pH to be 10. What type of buffer would you use?
