Challenge Problems
Push your limits with challenges.
Question 1
A pot contains 3 kg of water at 25°C. How much energy needs to be added to raise it to boiling point and then completely vaporize it? Specific heat of water = 4.18 kJ/kg°C and latent heat of vaporization is 2260 kJ/kg.
💡 Hint: Break it into two phases: heating to boil and then vaporizing.
Question 2
Explain how the concept of latent heat is pivotal for climate control in urban areas.
💡 Hint: Consider both air conditioning and heating systems in urbanization.
