Question

1. measure 10 ml of water into both the glass and plastic graduated cylinders.
2. observe the meniscus in both.
3. draw, label, and describe what happened in both, using the terms cohesion and adhesion.

answer the question then empty the cylinders and reset for the next group/class.
question: why does a meniscus form? (choose two that apply)
due to ionic bonding
adhesion and cohesion
due to the liquids attractive forces to the container or to itself
due to the liquids attractive forces to the container only

Explanation:

Meniscus forms because of adhesion (liquid - container attraction) and cohesion (liquid - liquid attraction). These are the liquid's attractive forces to the container or to itself. Ionic bonding is not relevant here. And it's not just attraction to the container (so the option with 'only' is wrong).

Answer:

adhesion and cohesion, due to the liquids attractive forces to the container or to itself
