Density And Pressure

We are given: - The coefficient of volume expansion of glycerine: , - Temperature rise: . The volume expansion coefficient is defined as the fractional change in volume per unit temperature change: This is the change in volume per unit volume. Since density is inversely proportional to volume, the fractional change in density is:
Thus, the percentage change in density is: Substitute the given values:
Thus, the percentage change in density is .
