Challenge Problems
Push your limits with challenges.
Question 1
A concrete bridge has a length of 50 m at 10°C. If the temperature rises to 40°C, calculate the change in length given that the coefficient of linear expansion for concrete is 1.0 x 10⁻⁵ °C⁻¹.
💡 Hint: Remember the formula for linear expansion.
Question 2
A gas in a container has a volume of 5.0 L at 25°C. If it is heated to 75°C, calculate the new volume assuming a constant pressure, and use the coefficient of volumetric thermal expansion for the gas as 3.0 x 10⁻³ °C⁻¹.
💡 Hint: Apply the volumetric expansion formula.
