The coffee with added table sugar would be considered a mixture. The table sugar dissolves in the coffee, creating a homogeneous mixture where the sugar molecules are evenly distributed throughout the coffee.
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.
Coffee doesn't have sugar unless it is added to the coffee.
It is sugar that is stirred and is dissolved faster than regular sugar.
homogenous
A cup of coffee with sugar dissolved in it is an example of a homogeneous mixture because the sugar is evenly distributed throughout the liquid.
Ground coffee as sold in grocery outlets does not contain any sugar. If it is used at all, sugar (or a sugar-free artificial sweetener) is typically added by the individual consumer at the time of brewing the coffee, in an amount that suits the individual's taste.
Coffee with cream and sugar 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.
Use only one teaspoonful of sugar on your cereal, there's already sugar in the ingredients.
Apparently it requires a special coffee bean and special roasting and a coffee expert that has a special skill.
When sugar is put into cold water and stirred, it will dissolve. The sugar molecules will disperse and mix evenly with the water molecules to form a sugar solution.
When a spoonful of sugar is added to half a liter of cold water, the sugar dissolves into the water, resulting in a sweetened solution. The sugar molecules break down and integrate with the water molecules, creating a homogenous mixture.
