Water (H2O) is a fundamental molecule for all living systems. The H2O molecules are capable of absorbing, storing, and releasing energy.

  • Water molecules are also capable of expanding upon freezing, dissolving and transporting materials.

  • Water reduces the viscosity and the melting temperature of both organic and inorganic compounds (e.g., rocks).

  • Water's polarity is responsible for most of its properties.

  • Water is a polar molecule because it has one oxygen (O) atom with a slightly negative charge and two hydrogen (H) atoms with a slightly positive charge.

  • In consequence, H2O can also be dissolved in other polar solvents.

  • For example, alcohols and carboxylic acids are compounds soluble in water due to the presence of a polar hydroxy or hydroxyl (-OH) group.

  • The most important water properties include polarity, cohesion, adhesion, specific heat, evaporative cooling, and surface tension.

  • Cohesion refers to the fact that hydrogen bonding holds H2O molecules linked together, whereas adhesion is because hydrogen bonding also holds water molecules with other molecules.

  • The cohesion of H2O molecules is capable of creating surface tension.

  • Specific heat refers to the amount of energy (in Joules) needed to raise the temperature of H2O molecules by one degree Celsius.

  • Water molecules have high specific heat, thereby enabling evaporative cooling to occur.

Answer:

number 3: The main properties of water are its polarity, cohesion, adhesion, surface tension, high specific heat, and evaporative cooling. A water molecule is slightly charged on both ends. This is because oxygen is more electronegative than hydrogen. The stream of water bends due to the polarity of water molecules.
