Question

determine whether each statement is true or false. adhesion is an attractive force between different types of molecules. adhesive forces hold water molecules together as water rises in a tube. a scoop - shaped concave meniscus forms when adhesive forces between a liquid and its container are stronger than cohesive forces between the liquid molecules. capillary action is only observed in plants. both adhesive and cohesive forces help move water from the roots of a plant to its leaves.

Explanation:

1. Adhesion is defined as the attractive force between different types of molecules, so the first statement is true.
2. Cohesive forces hold water - water molecules together. Adhesive forces are between water and the tube's surface. So the second statement is false.
3. When adhesive forces between a liquid and its container are stronger than cohesive forces between the liquid molecules, a concave (scoop - shaped) meniscus forms. So the third statement is true.
4. Capillary action is observed in many situations like water rising in a thin tube, not just in plants. So the fourth statement is false.
5. Both adhesive and cohesive forces are involved in the movement of water from plant roots to leaves through xylem vessels. So the fifth statement is true.

Answer:

1. True
2. False
3. True
4. False
5. True
