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

Answer

Brief Explanations:

  1. Cohesion is defined as the attractive forces between the same - type of molecules, so the first statement is true.
  2. Capillary action occurs when adhesive forces between water molecules and a container are stronger than cohesive forces between water molecules, so the second statement is false.
  3. A scoop - shaped concave meniscus forms when adhesive forces between a liquid and its container are stronger than cohesive forces between the liquid molecules, so the third statement is false.
  4. Cohesive forces do hold water molecules together as water rises from the roots of a plant to its leaves through the xylem, so the fourth statement is true.
  5. Water does not always rise to the top of a capillary tube. It depends on the diameter of the tube 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
