Question

determine whether each statement is true or false. cohesive forces hold water molecules together as water rises from the roots of a plant to its leaves. a scoop - shaped concave meniscus forms when adhesive forces between a liquid and its container are weaker than cohesive forces between the liquid molecules. capillary action may occur when cohesive forces between water molecules are stronger than adhesive forces between water molecules and a container. attractive forces between the same types of molecules is called cohesion. water always rises to the top of a capillary tube.

Explanation:

1. Cohesive forces among water - molecules are crucial for water to rise from roots to leaves in plants, so the first statement is true.
2. A concave meniscus forms when adhesive forces between a liquid and its container are stronger than cohesive forces between the liquid molecules, so the second statement is false.
3. Capillary action occurs when adhesive forces between water molecules and a container are stronger than cohesive forces between water molecules, so the third statement is false.
4. Cohesion is defined as the attractive forces between the same types of molecules, so the fourth statement is true.
5. Water does not always rise to the top of a capillary tube; it depends on the tube's diameter and the balance between cohesive and adhesive forces, so the fifth statement is false.

Answer:

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