Yes it is better.
The nouns are hand, cold, and water.
This type of heat transfer is called conduction. The transfer is from the warm hand to cool water.
When you dip your hand in cold water you feel it cold. Can you name the mode of heat transfer and its direction?
put your hand under cold runing water
hot water gets rid of bacteria, but then again, so does soap. warmer water would be better, but it doesn't really matter unless the cold water bothers you
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.

It's generally not necessary to remove the cups from a women's swimsuit when hand washing it. However, if the cups are removable and you prefer a gentler wash or want to prevent them from becoming misshapen, you can take them out. Be sure to follow the care instructions on the swimsuit's label for the best results.
The mode of heat transfer is conduction, where heat transmits from the warmer hand to the colder water molecules.
There is one bowl of hot water and one bowl of cold water and one bowl of warm water. You place one hand in the hot and one hand in the cold for approx. 30 seconds and then place your hands in the warm water and that hand that was in the hot water will feel cold and the hand that was in the cold water will feel hot. This is because the nerves have gotten used to the temperature and therefore have to adjust again to return to normal. Thanks! That helps a lot! I knew I had done it before but I couldn't remember what it was!
