Challenge Problems
Push your limits with challenges.
Question 1
A cylindrical tank with a radius of 0.5 m contains 500 liters of water at 25°C. If the water is heated to 75°C with a volumetric expansion coefficient of 2.1×10⁻⁴ °C⁻¹, determine the increase in volume and whether the tank can hold the expanded water.
💡 Hint: Convert liters to cubic meters first and think about the volume's total capacity.
Question 2
Explain the potential problems caused by liquid expansion in sealed containers under extreme heating conditions. How might this lead to failure of the container?
💡 Hint: Consider examples in everyday containers that could fail under pressure.
