Which process is described as endothermic and spontaneous at temperatures above 0 °C?
Understand the Problem
The question is asking to identify a specific process that is characterized as endothermic and spontaneous when temperatures exceed 0 °C. To solve this, we would need to evaluate the given options based on the definitions of endothermic and spontaneous processes in thermodynamics.
Answer
Melting of ice at temperatures above 0°C.
The melting of ice at temperatures above 0°C is an endothermic and spontaneous process.
Answer for screen readers
The melting of ice at temperatures above 0°C is an endothermic and spontaneous process.
More Information
As temperature increases above 0°C, the entropy change due to the state change from solid to liquid makes the melting process spontaneous despite being endothermic.
Tips
A common mistake might be confusing spontaneous with exothermic, but a process can be endothermic and still spontaneous due to a positive entropy change.
