A solid cube of side length 10 cm at 25 °C is heated. What will be the increase in its volume at 125 °C if its coefficient of linear thermal expansion is 9 × 10⁻⁶ K⁻¹? (Ans. 2.7 cm³)
Answer (2)
The increase in volume of the cube is calculated using the formula for volume expansion, given a coefficient of linear thermal expansion of 9 × 10⁻⁶ K⁻¹. The final result of the increase in volume when heated from 25 °C to 125 °C is 2.7 cm³. This is derived from the change in temperature and the original size of the cube.
