Yes, a cup is made out of matter.
Yes. Wet acetone will disolve sugar because of it's high water content, and although dry acetone will dissolve sugar, it will not do so in the way that wet acetone will.
Rice contains trace amounts of sugar in the form of starch. When starch is broken down in the body it is turned into sugar.
Lithium chloride is a chemical compound with the formula LiCl. The salt is a typical ionic compound, although the small size of the Li+ ion gives rise to properties not seen for other alkali metal chlorides, such as extraordinary solubility in polar solvents (83g/100 mL of water at 20 °C) and its hygroscopic properties
The contents of a cup of any hot liquid becomes diamond dust and ice when tossed out of the cup into the ambient air of Antarctica. This trick is generally more impressive during the season when there are no sunrises.

yes dissolving sugar in a coffee is a physical change in a chemical change a new substance will be formed, and the component of this substance will be different from the parent substance. but in the case of sugar dissolving in coffee, mixture of sugar and coffee retain their respective properties. Moreover we can also separate the constituents from that mixture.and there is no new substance is formed
no.
By flushing it in to the toilet
its as physical change as no reaction takes place. the sugar fills in the gaps between the water molecules so you cant see it un till you filter or dissolve the coffee.
Stirring sugar into a cup of tea is a chemical change because when you evaporate the tea you can not get the sugar back, instead you get a mixture of glucose and fructose. It is also a chemical change.
The cup of tea would become excessively sweet (sugary).
No it is a solution. A mixture is when you mix to substances together and they don't dissolve.
Hot tea is capable of dissolving more sugar than iced tea.
because the spoon is smaller making it harder to dissolve
The answer to this question depends on what you are focusing on. While it can be considered a change of physical state, the solid sugar becoming an aqueous solution, it can also be considered a chemical reaction, the sugar linking with the water and tea.
