A metal rod 2 m long increases in length by 1.6 mm, when heated from 0 to 60. The coefficient of linear expansion of metal rod is (a) 1.33 × 10⁻⁵/ (b) 1.66 × 10⁻⁵/ (c) 1.33 × 10⁻³/ (d) 1.66 × 10⁻³/

Answer: (a). α=(Δ L)/(LΔ T) α=1.6×10⁻³2× 60=1.33×10⁻⁵/° C So the answer is (a).

Thermometry & Thermal Expansion

A metal rod $2\text{ m}$ long increases in length by $1.6\text{ mm}$ , when heated from $0^\circ\text{C}$ to $60^\circ\text{C}$ . The coefficient of linear expansion of metal rod is

Show answer and solution

Answer: (a)

$\alpha=\frac{\Delta L}{L\Delta T}$
$\alpha=\frac{1.6\times10^{-3}}{2\times 60}=1.33\times10^{-5}/^\circ$ C
So the answer is (a).
