Question

select the true statements. when adhesive forces are greater than gravity, water rises in a capillary tube. cohesive forces between the glass tube and water molecules help water rise up a capillary tube. water rises to the same height in all glass tubes. adhesive forces between water molecules hold them together as they rise in a capillary tube.

Explanation:

Adhesive forces are the attractions between different substances. When adhesive forces between water and the capillary - tube material are greater than gravity, water rises. Cohesive forces are between like - substances, not between the glass tube and water (it's adhesive forces in that case). The height of water rise in a capillary tube depends on the tube radius, so it's not the same in all glass tubes. Adhesive forces are between different substances, and cohesive forces between water molecules hold them together as they rise. The first statement is correct as it accurately describes the condition for water rise in a capillary tube.

Answer:

When adhesive forces are greater than gravity, water rises in a capillary tube.
