Challenge Problems
Push your limits with challenges.
Question 1
Calculate the temperature of a gas sample given that its average kinetic energy is 4.5 J for 6 moles. Use \( k_B = 1.38 \times 10^{-23} \) J/K.
💡 Hint: Remember to find N using the number of moles and Avogadro's number.
Question 2
Two gases are mixed: one at 100 °C with mass 2 g and another at 50 °C with mass 3 g. Calculate the total kinetic energy of the system.
💡 Hint: Remember to convert temperatures to absolute scale (Kelvin) first.
