Hint: The cohesive force is dependable for the shape of the body, and therefore solid state has the fixed shape and size. Whereas adhesion is responsible, gum sticks to the paper. You might have read on the wrapper of fevi-quick it is written adhesive on it which is used to stick two parts.
Complete step by step answer:
Force of cohesion and force of adhesion
Force of cohesion – It can be defined as the force of attraction between the two same type of molecules and the substances to stick each other. It is an intermolecular attraction.
For Example – The formation of water droplets on the surface of the leaves during the rainy season is due to the cohesion.
Force of Adhesive - It can be defined as the force of attraction between the two different types of the molecules and the substances to cling to each other.
For Example – The spreading of the water molecules on the surface is due to adhesive.
Difference between the boiling or vaporization and evaporation
Boiling or Vaporization – It is the process at which liquid changes its state to gases above the boiling point of the liquid.
The most important factor of vaporization is that it takes place only when the substance reaches above its boiling point. For Example, water in the vessel starts vaporizing when it reaches temperature above its boiling point. (\[100^\circ C\])
Evaporation – It is the process at which the state of liquid is changed to the gaseous state when there is an increase in temperature and pressure.
Evaporation takes place at any place since the molecules of liquid absorb energy from the surroundings and change to the gaseous state. For Example, water in the pond or the river evaporates due to extreme heat and sunlight.
Note:Remember that the solids have high cohesive properties so they do not stick to each other, whereas liquids have both cohesive and adhesive properties and gases have weak cohesion properties.
