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!
It depends on the temperature of the tap water.
"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.
O.o
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.
Hot and cold are relative terms because what is considered hot or cold can vary depending on individual tolerance levels and perception. For example, a temperature that feels hot to one person may feel cold to another person. Additionally, what is considered hot in one region or season may be considered cold in another.

the process of moving thermal energy from one object to another due to a temperature difference. Heat transfer can occur through conduction (direct contact), convection (fluid flow), or radiation (electromagnetic waves).
If the objects are brought into contact with one another, it's very likely that heat will flow from the hot object into the cold one, and that their respective temperatures will tend asymptotically toward the same value.
one is hot and one is cold
When a person's hand is cold and the other is hot, this could mean many things. It might mean there is poor circulation through the cold one, or that they were laying on the one that is warm.
It will have two pipes one will be cold and one will be hot if one isn't hot or cold like it supposed to be it will be broken if one is hot and one is cold it is working?
It depends on the temperature of the tap water.
Probably Rubbing Alcohol or Listerine... OR OR Absenth
one is cold and the other is hot
one is hot and the other is cold.
No, a hot pan is not cold. A hot pan is one that has been heated and will be warm to the touch, not cold.
