  • What is cohesion in the context of water molecules?
    Cohesion is the ability of water molecules to stick to each other due to hydrogen bonding.
  • What is adhesion in relation to water?
    Adhesion is the ability of water molecules to stick to molecules that are not water, such as glass.
  • What type of bonding allows water molecules to exhibit cohesion?
    Hydrogen bonding allows water molecules to stick to each other, resulting in cohesion.
  • Why can water adhere to glass?
    Water can adhere to glass because glass is a polar object, allowing hydrogen bonds to form between water and glass.
  • How do cohesion and adhesion contribute to water’s surface tension?
    Cohesion and adhesion together give water a high surface tension, making it difficult to break the surface of the liquid.
  • What is surface tension?
    Surface tension is a measure of how difficult it is to break the surface of a liquid with force.
  • What property allows a paper clip to float on water if placed gently?
    The high surface tension of water, caused by cohesion and adhesion, allows a paper clip to float if placed gently.
  • Why are the cohesive and adhesive properties of water important for life?
    These properties are critical for water’s role as a solvent in biological processes.
  • What is an example of adhesion involving water?
    An example is water sticking to the surface of glass.
  • What is an example of cohesion involving water?
    An example is water molecules sticking to each other within a droplet.
  • Do most liquids display the same cohesive and adhesive properties as water?
    No, most liquids do not display the same cohesive and adhesive properties as water.
  • What allows water to hydrogen bond with other substances?
    Water can hydrogen bond with other polar or charged substances, enabling adhesion.
  • How does hydrogen bonding affect water’s properties?
    Hydrogen bonding is responsible for water’s cohesion, adhesion, and high surface tension.
  • What is the significance of water’s surface tension in nature?
    Water’s surface tension allows small objects, like insects or paper clips, to rest on its surface without sinking.
  • Why is understanding water’s cohesion and adhesion important in biology?
    Understanding these properties is essential for studying water’s role in biological systems and processes.
