If the water is room temperature, meaning the same temperature as the air, then you wouldn't feel a change in temperature. On the other hand, If there was a breeze or the air was otherwise in motion, it might increase evaporation of skin moisture and have a cooling effect. In that situation, putting your hands into the water might make them feel warmer.

Why does alcohol temp is low?
Actually alcohol at room temperature would be of the same temperature than water at room temperature. The difference between the two is that alcohol needs less heat to evaporate. If you wet either hand in alcohol and water, the one with alcohol will feel colder because it's removing more heat from you and faster. That's basically what cold is, the absence of heat.
Why do crystals dissolve in cold water?
they form so quickly in ice or in any other cold temperature because its so cold that when the crystals are forming its like its giving it a boost to growth.

The temperature of the water is lower than the air temperature. [Try running the hot water a little before you wash your hands.]

What happens if your hands are really cold and you put it in hot water?
the hot water will feel much hotter than it actually is. This is because the nerves that sense temperature feel cold or warm. Hot causes both types to fire. When your hands are cold, and you put them into hot water it can cause those nerves to fire more then they normally would. Also, if your hands are cold enough, the blood will be thickened, and the vessels will be constricted. Suddenly plunging your hands into hot water will cause the vessels to expand, sending the thickened, cold blood rushing up towards your heart which can cause a heart attack.
How can you prove hot and cold are relative term?
"Cold" and "hot" are the terms of describing temperature difference between two systems. To prove this, perform two trials in an experiment. If it is cold outside, do a trial with cold water from a faucet, spend some time outside, return to the faucet and then turn the cold water on again. Your findings will be that by changing your body's external temperature, you can feel the cold water that kept its temperature constant as relatively cold or warm. ________________________________________________________________ cold and hot are totallly relative term. it jst can be seen very much easily by a simple exp. jst take two beakers of water and in one put hot water nd in other put cold one. dip ur hands in it fr sme time n take ur hands out. you will notice dat your hand which was in hot beaker will feel cold sensation were as in other hand it will have hot sensation. here we can think the room temperature to be a critical point. so the hands being in cold beaker was having temperature lower were as in other it was viceversa.

How your hands will feel when you place them in the container of room temperature water?
Body temperature is regulated by an intricate system called homeostasis. If the external (outside) temperature is hotter or colder than our body then various things come into play to maintain our body heat. If you put your hand into room temperature water (room temperature is generally accepted to be 20 degrees C) then it will feel cold, because body temp is about 37 degrees C. The water will absorb heat energy from your hand, making it feel cold, until the temperature of the water and the temperature of your hand are the same. Or until you decide that shoving your hand in cool water is pointless...If you put your hand into water that is at 37 degrees C then you won't notice any temperature difference. It just feels wet. It's really weird, try it!
When you put one hand in hot water and one in cold water then both in tap water what do you expect to feel why?

What is that experiment with the two bowls with hot and warm water?
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!
What is the primary reason an ice cube feels cold to the touch?
Because the temperature of the ice is colder than the ambient temperature of your skin. The nerves near whatever you touch the ice with react to this temperature difference. This message is sent to your brain which then tells you something feels cold or hot.
