Question is for practice and not graded. Please elaborate on answer. Thank you.

Transcribed Image Text:**Question:**
Which of the following is always true for an endothermic process?
**Options:**
- \( q_{\text{sys}} < 0, \Delta S_{\text{surr}} > 0 \)
- \( q_{\text{sys}} > 0, \Delta S_{\text{surr}} < 0 \)
- \( q_{\text{sys}} > 0, \Delta S_{\text{surr}} > 0 \)
- \( q_{\text{sys}} < 0, \Delta S_{\text{surr}} < 0 \)
**Explanation:**
- **\( q_{\text{sys}} \):** Represents the heat absorbed or released by the system.
- **\( \Delta S_{\text{surr}} \):** Represents the change in entropy of the surroundings.
**Correct Answer:** The correct option is the second one: \( q_{\text{sys}} > 0, \Delta S_{\text{surr}} < 0 \), indicating that during an endothermic process, the system absorbs heat (positive \( q_{\text{sys}} \)), leading to a decrease in the entropy of the surroundings (negative \( \Delta S_{\text{surr}} \)).
