No, It doesn't. If you want to keep hot water hot for a longer time use a polystirene cup.
If the water in the cup came from the kettle, it will be cooler than the water that remains in the kettle. Since the water in the cup is more exposed to the air than the kettle it will lose heat to evaporation more quickly than the water in the kettle will. The cup will also conduct heat way from the water until the water and the cup are the same temperature, whereas the kettle is already as hot as the water it contains.
That depends on how hot the water is in the cup. Use the thermometer to measure it and see.
