Kinetic energy ratio from temperature
Particles in a mineral sample analysis warm from \(320\,\text{K}\) to \(348\,\text{K}\). Assuming average kinetic energy is proportional to kelvin temperature, calculate the ratio of final to initial kinetic energy. Use the diagram labels first, then answer carefully. 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.
