Salted tea

Electricity and Magnetism Level 1

Say I have two identical cups of tea, with equal volume and temperature. I pour into one cup a spoonful of salt, and the other I leave untouched. I stir both cups with identical rods at the same rate.

After some time, predict which cup will have a lower temperature.

Note: Salt doesn't react chemically with tea. Assume the salt is the same temperature as the tea.
