Question

The ciefficient of volume expansion of glycerin

Answer 1

Answer:

oefficient of volume expansion of glycerin, αV = 49 × 10–5 K–1

Rise in temperature, ΔT = 30°C

Fractional change in its volume =

This change is related with the change in temperature as:

Where,

m = Mass of glycerine

= Initial density at T1

= Final density at T2

Where,

= Fractional change in density

∴Fractional change in the density of glycerin = 49 ×10–5 × 30 = 1.47 × 10–2

Answer 2

Answer:

The coefficient of the volume expansion of glycerine is 49 × 10^-5 K^ -1.
