Challenge Problems
Push your limits with challenges.
Question 1
If the temperature of mercury in a thermometer rises from 10°C to 40°C, calculating the rise in volume should be done with a coefficient of expansion of 0.000018°C⁻¹. What volume change occurs for 2 mL of mercury?
💡 Hint: Follow the volumetric expansion formula step carefully.
Question 2
A thermometer calibrated from 0°C to 100°C has a maximum height of the mercury column at 65 mL. If the temperature increase is 35°C, how much mercury will rise in the tube? Assume the coefficient of thermal expansion is 0.000018°C⁻¹.
💡 Hint: Think about applying the change in temperature accurately to the original volume.
