Is sublimation an Endothermic or Exothermic process???

Endothermic. The material has to absorb heat to go from solid to gas form.

Sublimation is when a solid turns to a gas, skipping the liquid phase entirely, like with dry ice. I would say it's an exothermic process because the gas is warmer than the solid, so the process gives off heat.

The system will require heat to go from a solid to a gas so it is endothermic.

Endothermic. To separate the atoms of a solid to turn it to a liquid or gas, you need to do work.

Endothermic if it is going from a solid to a gas. It also increases in entropy.

It depends on the situation.
As the definition of sublimation is:
The transition of a substance from the solid phase directly to the vapor phase, or vice versa, without passing through an intermediate liquid phase.
SO if its from solid to gas form, its endothermic.
(and vice versa)

I would say Endothermic, but Im not totally sure.
