General Science (NDA) Physics

The coefficient of areal expansion of a material is 1.6 × 10^-5 K^-1. which one of the following gives the value of coefficient of volume expansion of this material?

0.8 × 10^-5K^-1

2.4 × 10^-5K^-1

3.2 × 10^-5K^-1

4.8 × 10^-5K^-1

Explanation:

The increase in the Volume of a body due to the increase in its temperature is called thermal expansion (Volume). Coefficient of volume expansion is given by, 3/2 x Coeff. of areal expansion = 3/2 x 1.6 x 10^-5K^-1 =2.4 x 10^-5K^-1
