Water is evaporated at any temperature because the movement of water molecules is continuous and some molecules at the surface can escape as a gas.
If you mean *exactly* one cup by volume, you have the iceberg scenario. The cup of frozen water will be less dense, so it will weigh less. If you just freeze a cup of water, don't spill any, and *don't* trim the excess to bring the volume back to exactly one cup, then it will weigh exactly what it did at room temp.
Yes, it is possible.
This is an experiment. it will change from liquid to solid.
The rate at which water evaporates depends on factors like temperature, humidity, and surface area, so it's difficult to give an exact time. In general, the process of water evaporating to three fourths of a cup could take anywhere from a few hours to a full day, depending on the conditions.
A cup of boiling water since it has higher temperature. Note that heat transfer depends more on the temperature.

None. Sugar goes into solution. Salt dissolves separating into Na and Cl attached to Water.
In the cup of boiling water, the water molecules have higher kinetic energy and move faster, leading to more chaotic movement. In the cup of ice-cold water, the water molecules have lower kinetic energy and move more slowly, resulting in a more orderly and structured movement.

Well, you can put it in a cup with room temperature water for a few minutes. Or in your mouth.
Room temperature is different in every room so I cant tell you what it is but I can tell you how to find out! Take any thermometer or a tool that measures heat (in celsius for your matter) and take a cup of water. Let the water sit for an hour inside the room that you find out the room temperature. Then put your thermometer in it and see what it measures to :) 20 degrees celcius
The same temp as the room it was placed in

That depends on the substance....water at room temperature weighs about 8.33 lbs per gallon....a cup is 1/16 of that, so water is .52 lbs per cup ....with 454g per lb, 1c water would be 238g
The water vapor in the air. Since the cup is so cold from the ice inside, the vapor in the air when it hits the cup it causes it to make the water on the outsaide of the cup. You'd think it came from the inside, but it doesn't.
