Question

what do you mean by coefficient of cubical expansion of mercury is 1.8*10^5°c^-1?​

Answer 1

Answer:

The volume expansion at 100 °C is given as,

AV = =Voy x AT

= 10-6 x 18 x 10-5 x 100

= 18 × 101 -9 m³

The length of the mercury column is given as,

1= AV A

18 × 10-⁹ 4 x 10 = 4.5 x 10 -7 -2 m

Thus, the length of the mercury column is 4.5 cm.
