Challenge Problems
Push your limits with challenges.
Question 1
Assess the energy absorption in a scenario where a glacier melts completely due to rising temperatures. Assuming a glacier mass of 1,000,000 kg and a latent heat of fusion of 334,000 J/kg, calculate the heat absorbed.
💡 Hint: Follow the same formula we learned for smaller masses.
Question 2
Investigate the role of latent heat in the process of making ice cream using an ice and salt mixture while understanding the heat dynamics involved.
💡 Hint: Focus on the changes that occur during the mixing process.
