One of the problems with water in a thermometer is the effect of capillary action - the column of water tends to "stick" to the sides of the thermometer and create a U-shaped surface at the top. This makes it very difficult to read the thermometer. Previously Mercury was considered to be a good medium for thermometers, but this has been discontinued due to the health risks from a broken mercury thermometer; the current medium in thermometers is dyed ethanol or methanol.
That depends on how hot the water is in the cup. Use the thermometer to measure it and see.

I usually use a cheese thermometer. They are very accurate.
its rate of expansion is to great.
Water freezes at a fairly high temperature - 0oC/32oF. As soon as the temperature reached that point the water would freeze and the thermometer would no longer work. One would not be able to use a thermometer with water in it to measure any temperatures below 0oC/32oF.
I would use a thermometer.

Use a thermometer. =====================
About 10 minutes.
Use a thermometer.
I would use a thermometer.
the mercury should be at normal body temperature level before using it the thermometer should be cleaned after use with normal water the bulb of the thermometer should not be touched

yes
No.
The easiest way is with a floating thermometer.
When calibrating any kind of thermometer in an ice water bath, the temperature should be 0o C or 32o F.
