(N/A) Particles of sugar crystals occupy the empty spaces between the particles of water,hence the volume does not increase significantly.
$(b)$ The water in the wet cloth absorbs excess heat from the body due to the high latent heat of vaporisation,which helps in lowering the body temperature.
$(c)$ Naphthalene balls undergo sublimation,where they directly convert from a solid state to a gaseous state without leaving any residue.
$(d)$ $A$ wooden table has a fixed shape,a fixed volume,and is rigid and incompressible,which are the characteristic properties of a solid.
$(e)$ Dogs hang out their tongues to increase the surface area for the evaporation of saliva,which causes a cooling effect on their body.
