The graph between magnetic susceptibility and absolute temperature fo...
Explanation:
Hyperbola:
- The graph between magnetic susceptibility and absolute temperature for a paramagnetic substance is a hyperbola.
- In a paramagnetic substance, the magnetic susceptibility decreases as the temperature increases.
- This relationship is described by the Curie-Weiss law, which states that the magnetic susceptibility is inversely proportional to the absolute temperature (χ ∝ 1/T).
- Mathematically, this relationship can be represented by a hyperbolic curve on a graph, where the magnetic susceptibility decreases asymptotically as the temperature approaches absolute zero.
- This behavior is typical for paramagnetic materials, where thermal energy disrupts the alignment of magnetic moments resulting in a decrease in magnetic susceptibility with increasing temperature.
Key Points:
- Paramagnetic substances exhibit a hyperbolic relationship between magnetic susceptibility and absolute temperature.
- The Curie-Weiss law describes this relationship as χ ∝ 1/T.
- The graph shows a decrease in magnetic susceptibility as temperature increases.
Therefore, the correct answer is option D - Hyperbola.
