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!
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?
It depends on the temperature of the tap water.
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.
If one object is hot and the other one is cold they have different?
O.o
Why does warm water rise and cold water sink?
Actually you are wrong, its vise versa, hot water rises and cold water sinks. This is because when water molecules gain energy, they become hot. Molecules try to move away from one another. And this leads to reduction in density. Since density of water reduces as it becomes hot, how water moves up and cold water sinks down.
