Challenge Problems
Push your limits with challenges.
Question 1
A gas undergoes a reversible isothermal expansion from an initial volume of 5L to 15L at 350 K. Calculate the work done and the change in entropy when 100 J of heat is absorbed.
💡 Hint: First calculate the work using the right gas law principles, then apply to the heat absorbed.
Question 2
Determine the total change in entropy for 3 kg of ice melting at 0 °C to water at the same temperature, given Lf = 334 kJ/kg.
💡 Hint: Think carefully about the conversion of energies and make sure your values are in consistent units.
