Water Transport Bonds Cohesion Molecules Explain Polar Nature

Water's polarity and hydrogen bonding contribute to its thermal stability and cohesion, making it an effective transport medium via capillary action.

Water's polar nature and the resulting hydrogen bonds enable thermal stability and cohesion, allowing it to act as an effective transport medium through mechanisms like capillary action.

Front Explain why the polar nature of water allows it to be a useful transport medium.
Back Water as a transport medium
  • The hydrogen bonds allow for thermal stability - remains a liquid over a big range of temperatures
  • Cohesion between water molecules means that when water is transported through the body, molecules stick together (hydrogen bonds between water molecules)
  • Cohesion and adhesion allow for capillary action
