How stirring a liquid affects temperature measurements.
1. The problem statement, all variables and given/known data
"Some people say stirring a hot liquid with a thermometer gives a better measurement and some say it yields a worse measurement. Explain with physics how one is actually better"
2. Relevant equations
None that I know of.
3. The attempt at a solution
I know that stirring a liquid generally cools it, but I was also thinking that the increased kinetic energy due to the stirring may cause an increase in temperature. Also, stirring would evenly distribute the liquid so that the average temperature would be more measurable, but if it changes the temperature through the previously stated ways, then wouldn't it be worse?

That's great thank you so much! I was leaning toward that answer but didn't have much of a justification.
