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.
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 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.

It depends on the situation. If cold and hot water were mixed roughly together, they will simply mix with each other.

In a small container, they will also mix immediately.
