Question

A 100cm3 measuring cylinder made from Pyrex glass is filled with glycerin to the

50cm3mark at 20oC. If the cylinder and content is heated to 40oC, to what mark will the

Glycerin rise? Take 𝛾𝑔𝑙𝑎𝑠𝑠 = 3 𝑥 10−6 𝑜𝐶 and 𝛾𝑎𝑙𝑐𝑜ℎ𝑜𝑙 = 500 𝑥 10−6 𝑜?

Answer 1

$\gamma=\frac{\Delta V}{V_1\Delta T},\implies$

$V_2=V_1(1+\gamma\Delta T)=50.003~\text {cm}^3.$
