Question

Water has the property of adhesion because

it has a high specific heat

covalent bonds hold an individual water molecule together

it has a great deal of kinetic energy

hydrogen bonds form between adjacent water molecules

hydrogen bonds form between water molecules and hydrophilic substances

Answer 1

Water has the property of adhesion because --> It has surface tension

It has a high specific heat --> hydrogen bonds form between adjacent water molecules

Due to the presence of hydrogen bonds and strong intermolecular forces, water exhibits high surface tension. So, water molecules on the surface are more strongly attracted to each other than to the air above. The high surface tension of water makes the alveoli to produce a surfactant, which prevents their collapse. The surfactants lower the surface tension.

Because of the hydrogen bonding, and strong intermolecular forces, water has a high specific heat index. The specific heat capacity of water is defined as; the amount of heat (energy in joules) required for raise of the temperature of water per unit mass by 1⁰C. The specific heat capacity of water is 4.18Joules.
