Question

The coefficient of linear expansion of aluminium is 24×10-6 ºC-1. What would be its value in the SI unit?

OR

From which law is the value of the volume expansion coefficient of gas obtained?

WBBSE Class X Physical Science Behaviour of Gases 01 Mark 2024

Answer

Coefficient of linear expansion of aluminium = 24 × 10⁻⁶ °C⁻¹.
Since 1 °C change = 1 K change, its SI unit value is 24 × 10⁻⁶ K⁻¹.

OR

The value of the volume expansion coefficient of a gas is obtained from Charles’ law.
