Physics · JEE | THERMAL PROPERTIES OF MATTER
हिन्दीGiven below are two statements: Statement I: The coefficient of volume expansion \( \alpha_v \) for an ideal gas is inversely proportional to its absolute temperature \( T \). Statement II: Water exhibits anomalous behavior by contracting on heating between \( 0^\circ\text{C} \) and \( 4^\circ\text{C} \). In the light of the above statements, choose the most appropriate answer from the options given below:
View Answer & Solution
Correct answer · Option A
Both Statement I and Statement II are correct.
Explanation
For an ideal gas, \( \alpha_v = 1/T \) (Eq. 10.6), and water contracts when heated from \( 0^\circ\text{C} \) to \( 4^\circ\text{C} \). Both statements are correct.
