IB skill practice

Use Kelvin temperature and particle kinetic energy

Paper 1, Paper 2 5 marks Difficulty 4

Kinetic energy ratio from temperature

Particles in a water treatment demonstration warm from \(295\,\text{K}\) to \(329\,\text{K}\). Assuming average kinetic energy is proportional to kelvin temperature, calculate the ratio of final to initial kinetic energy. Enter the answer and choose the interpretation that matches the chemistry.

Worked practice: chemistry evidence and answer

Use the chemical evidence first, then enter the result and interpretation that match it.
