## Homework Statement

hi, i have a lab for thermal physics in which the cooling of coffee is monitored. The variable change is the amount of milk that is added once the coffee is brewed. My question is whether there is an equation that relates heat exchange between 2 liquids in a solution? (an equation that also accounted for the room temperature would be even more helpful)

## Homework Equations

mcΔT = mcΔT

## The Attempt at a Solution

i know that the above equation due to law of conservation of energy where m is mass, c is heat capacity, and ΔT is temperature change. However, this one only finds a final temperature. I wanted an equation that would take into account for time. Thanks.
