<h2>Hey There!</h2><h2>_____________________________________</h2><h2>Answer:</h2>
Sublimation is a process in which the solid molecules gain energy from their surrounding and they now have enough energy to overcome the force of attraction with the neighboring molecules, thus they escape into the surrounding without going through the liquid phase, that means they directly jump to the vapor phase.
<h2>_____________________________________</h2><h2>Endothermic</h2>Those process which absorb energy from their surrounding to form the product are called endothermic process. Since the SUBLIMATION requires additional energy, it is an endothermic change.
