Q. For a given substance, the coefficient of volume expansion is approximately __________ the coefficient of linear expansion.

किसी दिए गए पदार्थ के लिए, आयतन विस्तार का गुणांक रैखिक विस्तार के गुणांक के लगभग __________ है।

A
Same
वही
B
Double
दोहरा
C
Three times
तीन बार
D
One-third
एक तिहाई

Explanation

The coefficient of volume expansion (γ) is related to the linear expansion coefficient (α) by:

γ≈3α\gamma \approx 3\alpha

This is because volumetric expansion occurs in three dimensions (length, width, and height), making the total effect approximately three times the linear expansion.
