Question

determine whether each statement is true or false. 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. adhesion is an attractive force between different types of molecules. both adhesive and cohesive forces help move water from the roots of a plant to its leaves. adhesive forces hold water molecules together as water rises in a tube.

Explanation:

1. When adhesive forces between a liquid and its container are stronger than cohesive forces between liquid molecules, a concave meniscus forms. So the first statement is true.
2. Capillary action is observed in many places like in narrow tubes in laboratories, not just in plants. So the second statement is false.
3. Adhesion is indeed an attractive force between different - types of molecules. So the third statement is true.
4. Adhesive and cohesive forces work together in the process of transpiration - pull in plants to move water from roots to leaves. So the fourth statement is true.
5. Cohesive forces hold water molecules together as water rises in a tube, not adhesive forces. So the fifth statement is false.

Answer:

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