Question

Quizplus · Accepted Answer

The average molecular kinetic energy is directly proportional to the temperature. Therefore, ΔKE ∝ ΔT. The temperature has increased by a factor of 3, so the average molecular kinetic energy has also increased by a factor of 3. Therefore, K₁ = 0.33 K₂. Solving for K₁, we get K₁ = 0.88 K₂.
