Does sublimation release energy?
Understand the Problem
The question is asking whether the process of sublimation, which involves a substance transitioning from a solid to a gas, releases energy. This requires an understanding of thermodynamics and phase changes.
Answer
Sublimation is an endothermic process.
Sublimation is an endothermic process.
Answer for screen readers
Sublimation is an endothermic process.
More Information
Sublimation requires the absorption of heat to provide enough energy for molecules in the solid phase to escape into the gas phase.
Tips
A common misconception is believing sublimation releases energy because changing state generally involves energy exchange.
