In the context of thermodynamics, what does it mean for a process to be 'spontaneous'?

  • A: It occurs very quickly and instantaneously.
  • B: It requires a continuous input of energy to proceed.
  • C: It leads to a decrease in the overall entropy of the universe.
  • D: It is energetically favorable and proceeds without requiring an input of energy, leading to an increase in entropy.

Explanation

The text defines a spontaneous process as one that, 'by itself, leads to an increase in entropy, that process can proceed without requiring an input of energy.' It also clarifies that 'spontaneous' means 'energetically favorable'.
