The coefficient of volume expansion of glycerin is `49xx 10^(–5) K^(–1)`. What is the fractional change in its density for a `30^(@)C` rise in temperature ?

Explanation

Given, coefficient of volume expansion `gamma =49xx10^(-5)C^(-1)` Temperature `T= 30^(@)C` Let `p_(o)` its density at `0^(@)C, P_(t)` its density at `t^(@)C.`
`therefore` Fractional change in density,
`(P_(o)-Pt)/(P_(o))=gammaDeltaT=49xx10^(-5)xx30=0.0147`
