Physics · Thermal Properties of Matter
A copper rod and a steel rod have lengths LC and LS respectively, such that the difference between their lengths remains the same at all ambient temperatures. If the coefficients of linear expansion of copper and steel are αC and αS respectively, how are their lengths related to their coefficients of linear expansion?

- 1LC / LS = αC / αS
- 2LC / LS = (αC / αS)1/2
- 3LC - LS = αC - αS
- 4LC / LS = αS / αC✓
Correct answer
LC / LS = αS / αC
