The value of coefficient of volume expansion of glycerin is

5 \times {10^{ - 4}}{\mathrm{K}^{ - 1}}

. The fractional change in the density of glycerin for a rise of

\mathrm{40^\circ C}

in its temperature is:

View answer and explanation

Correct option: C

0.020

Option C (0.020) is correct because the fractional change in density is directly proportional to the coefficient of volume expansion and the temperature change.
