In a coffee press, you combine solid coffee grounds and hot water. After a long time, the ground coffee beans are still visible, and the water has turned into a rich dark brown (some of the coffee has dissolved into the liquid). You push the filter in the press down and pour out only the dark water into a cup. You then add milk and sugar to the cup. You also notice that the filter must have a hole in it because there are coffee grounds also in your cup. Calculate the degree of freedom in this system (your cup) at equilibrium. 1 2 3 4
