Wet hand Syndrome?
When water touches your hand, you may feel sensations such as wetness, coolness, and possibly a slight sensation of pressure or movement depending on the temperature and flow of the water.
The temperature differences - if the water temperature is cooler than the temperature of your hand, your hand will lose heat to the water. Furthermore, when the remaining droplets of water on your hand evaporate, it will also take some of the heat it absorbed from your hand.

When you dip your hand in cold water you feel it cold. Can you name the mode of heat transfer and its direction?
The water vapor directly above the pot would feel warm and moist on your hand. It would create a sensation of heat and dampness due to the evaporation of the boiling water.
This type of heat transfer is called conduction. The transfer is from the warm hand to cool water.
warm to hand slightly cold
it means she wants to hold your hand
It depends on the temperature of the tap water.
feel cold water in the head
This is due to the phenomenon known as contrast effect. When you first put your hands in cold and hot water, your nerves respond to the extreme temperatures. When you move them to the lukewarm water, the hand that was in the cold water will perceive the water as hot because of the contrast in temperatures.
The mode of heat transfer is conduction, where heat transmits from the warmer hand to the colder water molecules.
