What are 'irreversibilities'?

Correct answer: Factors that render a process irreversible.

Explanation

This question assesses the conceptual understanding of 'Irreversibilities' as the real-world factors (like friction, unrestrained expansion) that prevent a process from being perfectly reversible.
