Question

A 50 cm3 Pyrex container is filled with 45 cm3 of Acetone in hopes of not spilling when both materials are heated from 24°C to 44°C.

Is there a spill of Acetone?

How much?

Answer 1

Ans: 0.147 cm³

Explanation:

Here volume of the Pyrex container , V = 50 cm³

Volume of Acetone , V' = 45 cm³

Change in temperature , ∆T = (44-24)°C = 20°C

coefficient of volume expansion of Pyrex glass ,

Coefficient of volume expansion of Acetone ,

Final volume of the Pyrex container after heating from 24°C to 44°C

Final volume of Acetone after heating ,

Since V'>V , there is a spill of Acetone.

∆V = V'-V = (50.15-50.003) cm³ = 0.147 cm³

0.147 cm³ acetone will spill out from the container.
