Question

water can travel up a glass tube against the force of gravity! this is called capillary action.
the model shows what happens when a thin glass tube is placed in a beaker of water.
complete the sentences.
forces cause water molecules to stick to the glass molecules in the tube. forces between water molecules hold the molecules together. when forces are greater than the forces, water appears to climb up the tube.

Explanation:

Step1: Define adhesion

Adhesion is the attraction between different substances. In capillary action, adhesion forces cause water molecules to stick to the glass molecules in the tube.

Step2: Define cohesion

Cohesion is the attraction between like - substances. Cohesion forces between water molecules hold the molecules together.

Step3: Compare forces

When the combined adhesion and cohesion forces are greater than the gravitational forces, water appears to climb up the tube.

Answer:

Adhesion; Cohesion; Adhesion and cohesion; Gravitational
