1) The latent heat of vapourisation of heat

Condensation

2) Yes it is true that sublimation does not require heating . Sublimation is a process of conversion of solid into vapor state and vapour into solid state without coming in liquid state. ... And this happens not because of heat it is a natural phenomenon as it gains the heat from the surface .

3) Solid is the state in which matter maintains a fixed volume and shape; liquid is the state in which matter adapts to the shape of its container but varies only slightly in volume; and gas is the state in which matter expands to occupy the volume and shape of its container.
