The value of coefficient of volume expansion of glycerin is 5 10^-4 K^-1. The fractional change in the density of glycerin for a rise of 40^ C in its temperature is

Question

Accepted Answer

Correct answer: B. (b) Given, r=5 10^-4 K^-1 As, original density of glycerin, = _0 (1+ T ) ⇒ - _0= _0 T T=40^ C - _0 _0= T=5 10^-4 40=200 10^-4=0.020

$The value of coefficient of volume expansion of glycerin is . The fractional change in the density of glycerin for a rise of in its temperature is$
