### #7 - The Physics Tea Riddle

On a beautiful Sunday morning, You ordered a hot team to your hotel room and suddenly you remember an important thing that needed to be done right now will take around 3 minutes to complete.
Like most people you like your tea to be hot while drinking so, when should you pour cream in the tea ?
1. straight away
2 Just people, you drink the team
3. Its do not matter

The heat transfer is driven by the fact of the temperature difference between two objetcs. Since initially tea is very hot so temperature difference is high and hence it will cool down fast.
Now when we add cream to team it not only increase the mass of tea (more mass and hence more time to cool) but also adding cream to tea will bring down the temperature instantly but later will cool down slowly. Hence cream should be added Straight away.
