Yes, until you add creamer. While it has lighter and darker swirls it is heterogeneous. Once you stir the creamer in and it is all the same color it becomes homogeneous again.
If you have added milk and/or sugar to your hot coffee, you will have to stir it well, in order to obtain a homogeneous mixture.

Yes. Black coffee is a homogeneous mixture.
Coffee is a homogeneous mixture (assuming it has been well-stirred), as the mixture has a uniform composition throughout. Dividing the mixture into macroscopic parts, each part will have the same composition as the original mixture.

Hot coffee is a solution, not a suspension. No matter how long you wait, the coffee does not settle out to the bottom of the cup.
A cup of coffee is a homogeneous mixture. No matter what one uses to sweeten or lighten it, the coffee is the same in every sip.

A hot cup of coffee will cool down at a certain rate, but as the coffee cools, the rate at which it cools slows down. This is why a "lukewarm" cup of coffee cools down so slowly. Even though the warm cup of coffee is cooling down quicker at first, the lukewarm cup essentially has a "head start" on the way to room temperature.
Hot coffee is a solution, not a suspension. No matter how long you wait, the coffee does not settle out to the bottom of the cup.
When you stir a cup of coffee, the energy of the coffee is initially raised from the bottom of the cup. This can causeÊthat hot coffee to cool quicker, but it depends on the temperature of the cup and the coffee's surface.
Yes.
