Which physical changes are endothermic?
Understand the Problem
The question is asking to identify and explain which physical changes absorb heat energy from the surroundings, indicating an endothermic process. This typically involves changes such as melting, evaporation, and sublimation.
Answer
melting, vaporization, and sublimation
The final answer is melting, vaporization, and sublimation.
Answer for screen readers
The final answer is melting, vaporization, and sublimation.
More Information
Endothermic processes absorb heat from their surroundings, leading to a temperature decrease in the surroundings. These processes result in phase changes requiring energy input.
Tips
A common mistake might be confusing condensation and freezing as endothermic. Remember that condensation and freezing release heat, so they are exothermic.
