Question

If thermal cofficient of linear expansion of metal is 1.5 × 10–5 °C–1 then its thermal coefficient of volume expansion is

Answer 1

Answer:

thermal coefficient of volume expension is 45×10^-6/°C

Explanation:

We know that the volume of a body is given as:

[V]=L ^3

Therefore, the relation between the coefficient of linear expansion and volume expansion is written as:

coefficient of volume expansion= 3 * coefficient

of linear expansion

• γ=3α

γ=3×15×10 ^−6

coefficient of volume expansion γ=45×10 ^−6 /°C
