Which of the following is an endothermic process?
- A Condensation of water vapor
- B Sublimation of dry ice
- C Combustion of paper
- D Freezing of water
That's Correct!
It's Wrong!
Endothermic processes absorb heat from their surroundings, and sublimation is one such process where a substance transitions directly from a solid to a gas without passing through the liquid phase. In the case of dry ice (solid carbon dioxide), sublimation occurs at temperatures and pressures where it goes from a solid to a gaseous state, absorbing heat in the process.
