Challenge Problems
Push your limits with challenges.
Question 1
A copper pipe expands when heated from 10°C to 70°C. Given its original length is 4m and the coefficient of linear expansion for copper is 16.5 x 10^-6 °C^-1, calculate the change in length.
💡 Hint: Use the linear expansion formula correctly.
Question 2
Consider a glass jar filled with water. If the jar's volume changes by 200 cm³ due to thermal expansion, what is the new volume if the original volume was 1500 cm³?
💡 Hint: Simply add the changes to the original volume.
