What is the operational definition of temperature?

The sensation of hot and cold
The movement of energy from one place to another
The quantity measured with a thermometer (correct)
The average kinetic energy of translation

What does temperature being proportional to the average kinetic energy of translation imply?

Average kinetic energy of translation is not related to temperature
Higher temperature means higher average kinetic energy of translation (correct)
Lower temperature means higher average kinetic energy of translation
Higher temperature means lower average kinetic energy of translation
