Properties of Water

  • An unequal distribution of charges affects H20 by making it polar

  • Cohesion is when two molecules of the same substance stick together

  • Surface tension is when a surface of a liquid is difficult to stretch 

  • Adhesion is when two different molecules stick together (forms stronger bonds than cohesion

  • Capillary action is water travelling up a small enclosed tube, against gravity

  • Capillary action can be helpful for plants to soak up nutrients in order to grow and develop

  • High specific heat capacity is when energy is used to raise the temperature of water (helps regulate cell temperature in organisms)

  • Solute is what’s being dissolved

  • Solvent is the substance that does the dissolving

  • Solution is the uniform mixture of one or more substances

  • Water is polar because it has one oxygen atom that is negative and two hydrogen atoms that are positive

  • A pH less than 7 is acidic

  • A pH more than 7 is basic

  • A pH that is 7 is neutral

  • Acids contribute H+, bases contribute OH-
