Should you pour the milk now, or after you come back? Or does it make no difference? Would like to add the milk into coffee after I come back. Because the hot coffee without milk will cool longer than the warm coffee with milk. Aim: To find out the relationship between the time at which the milk is added, and the final temperature of the coffee/milk mixture. Every minute the coffee was getting cooler (milk was getting warmer until the room temperature), but when we added the milk into coffee it started to cool more faster.

Also we use only one thermometer in short time, after hot coffee we measured the temperature of the milk promptly, maybe this can changed results. To solve these problems we should use woo metal rods and two thermometers. Make sure you read and follow the checklist!!!!!
