The coefficient of volume expansion of glycerine is `49 xx 10^-5 ^@C^-1`. What is the fractional change in its density for `30^@C` rise in temperature?

Text Solution

Verified by Experts

We are given :
`alpha_(v)=49xx10^(-5)K^(-1)`
`DeltaT=30^(@)C`
We are to calculate , change in density , `Deltarho`
Using relation : `(Deltarho)/(rho)=alpha_(V)DeltaT=49xx10^(-5)xx30=1.47xx10^(-2)`.
