कौन-सी सांद्रता तापमान बदलने पर भी नहीं बदलती?

Which concentration term does not change with temperature?

Explanation opens after your attempt
Correct Answer

B. मोललता / Molality

Step 1

Concept

Volume may change with temperature, but mass does not.

Step 2

Why this answer is correct

Molality is based on mass of solvent, so it is not affected by temperature. Molarity depends on volume and may change.

Step 3

Exam Tip

For temperature-based questions, identify mass-based concentration terms. चरण 1: तापमान बदलने पर आयतन बदल सकता है, पर द्रव्यमान नहीं बदलता। चरण 2: मोललता विलायक के द्रव्यमान पर आधारित होती है, इसलिए यह तापमान से प्रभावित नहीं होती। मोलरता आयतन पर निर्भर होने से बदल सकती है। चरण 3: तापमान संबंधी प्रश्नों में द्रव्यमान आधारित सांद्रता को पहचानें।
