Question

We would like to make a vessel whose volume does not change with temperature (take a hint from the problem above). We can use brass and iron ( β_vbrass = 6 × 10^–5/K and β_viron = 3.55 ×10^–5/ K) to create a volume of 100 cc. How do you think you can achieve this.

Answer 1

Iron vessel with a brass rod inside

(V_iron / V_brass) = 6/3.55

V_iron - V_brass = 100cc = V_o

V_bress^rod = 144.9cc  V^inside_iron = 244.9cc
