During sublimation, heat is added to the substance. This process involves a solid transforming directly into a gas without passing through the liquid phase, which requires energy in the form of heat to overcome the intermolecular forces holding the solid together. As a result, the temperature of the solid decreases while it absorbs heat, enabling the transition to the gaseous state.
In condensation heat is removed In evaporation heat is added
Sublimation is an endothermic physical change (heat is needed).
Of course heat is added because you are turning solid which is like ice to gas which is water vapour !!
Heat energy is being added during boiling to change the liquid into vapor. This added heat energy causes the molecules in the liquid to overcome the intermolecular forces holding them together, leading to the phase change.
added
An adiabatic process is when there is no heat exchange with the surroundings. This means that no heat is added or removed from the system during the process.
Changes in the state of matter occur when the amount of heat energy is changed in a substance. When it is removed, gas condenses and liquid freezes. When it is added, solids melt and liquids boil.
Heat is absorbed during sublimation, as the process involves a solid turning directly into a gas without passing through the liquid phase. This requires energy input to break the intermolecular forces holding the solid together and to overcome the forces of attraction between the solid molecules.
Because the object becomes hot when heat is added.

heat
Sensible heat is the term used to describe heat that is added or removed from a substance without changing its state. It relates to the temperature of the substance and can be measured using a thermometer.
