if i put my finger in hot water, then touch metal pot, why i will fill less pain in water than in metal pot?

Water evaporates at 100 degrees, celsius, so the liquid water you touched wouldn't be any hotter than that. The metal, on the other hand, does not. So it would be as hot as the object which is heating it.

Well you pushed the bones together. Normal you have a space between the bones and you jammed it pushed the bones together and that puts the pain and bruising on the finger. Sorry hope it gets better soon.

your finger tips are used more often.\nit's easier to tell if an egg is about to break because you are squeezing it too hard, or if something you grab is too hot.

Basically you dehydrated your cells in your skin. The h20 your skin has decreased too rapidly. That water helps to keep you from buring. Place two metal objects in the sun and then add water ontop of one. within a few minutes the dry one will become much hotter. When the water evaporates off the other one it too will becomoe the same temp. Your skin is the same way if you stay in the sun for too long you dried out your skin. The itch is from the sensor receptors getting fried as well as from pealing. The pealing occurs because of of the damaged dryed out skin and the new skin is forming underneath.

You have sensitive teeth and the compounds in the beverage activate the pain receptors.  It is has some thing to do with the electrolytes in the brew

I believe the answer to your question lies on the amount of humidity in the air and the moisture content of your fingers...\n\nLiken it to putting your tongue on a cold metal pole outside in the winter. the moisture on your tongue in the form of saliva immediately freezes on contact with the metal pole.\n\nSomething similar happens when ice cubes stick to your fingers. The moisture in your finger tip immediately freezes on contact with the ice. Hence the sticking.... On dryer days, your fingers are dryer, and there is no sticking.\n\nHope this helps.

Because the atoms in heated water are farther apart.  It actually makes the water less dense.  It then becomes easier to freeze less dense liquid.

I used to work for a wire company and it sometimes ran the wire through a part of the machine called the Hi Pot test it would run 10,000 volts through the wire and if it burned through the insulation than the machine would stop and you would cut the defected wire away and retired the machine but I would get shocked every time the hi-pot machine would kick off.  It made my mussels contract abit and made me jump.  Some times when I didn't have money for coffee I would stick my finger in the hipot to get a zap to wake up. It hurt a little but it woke me up just the same.  Any how it isn't the Volts that kill you it is the Amps.  The Higher the Amps the greater the current is.  Like you could get killed with only 12 volts if the amps are high.  consider Water the smaller the hole the faster the water goes because of pressure.  Well Amps are like that.  The Higher the Amp the greater the pressure.

You would find, if you had a sensitive enough measuring system, that the energy is dispersed through the acid as heat. \n\nWhen acid oxidises metal there is an initial activation energy required to break the metal lattice and that energy nromally comes from the heat already in the system. When the lattice is under stress sit requires far less energy to break down and the activation energy is lower. That means that more heat is retained by the system as heat.\n\nYou can see for yourself that a metal lattice under stress breaks down and oxidises more readily by simply bending an iron nail and dropping it in a few mm of salt water for a few days. The iron will rust almost exclusively where it was bent. That is because the  bend represents a point of stress in the lattice.\n\nWith less energy required to break down the metal alttice the overall reaction becomes more energetically positive and the amount of heat in the system increases.\n\nThe amount of additional heat this represents is tiny, but with an incredibly stable atmosphere and a very sensitive thermometer you would regeister the lost energy as a higher temperature than an identical beaker of acid with an uncompressed spring.

Because the earthern pot has pores in it . By which some water droplets comes out & evapourate. During evapouration some heat is absorbed from the pot .\nHence the pot cools down & the water also.

The metal spoon is a good conductor of heat. It also has a handle that protrudes out, with a fair amount of surface area to radiate heat out, and the spoon will also cool by convection. This definitely will cool the coffee down faster.

I think water you know that the tap wtaer is hard water i.e it contains excess of Ca++ ions and also the water is made up up of h20 which is ionic in nature and now the the original part when the person touches the switch cause the person is covered all of his body with hard water which is a 98.456% conductor of electricity he gets a svere shock also you should be knowing humanbody is also a conductor of electricity blood is acetic so both media media make good conductors of electricity and no obstruction is observed. In this way the person may also die.\n so always when working with electricity wear rubber slippers which are insulators (dont conduct current).\n GO ON KEEP ASKING

No, that is not true.  If you have a more dense metal, it may take more energy to heat it up, but that is because there is more mass.  Water has a very high specific heat, but it is definately less dense than metals.  I believe specific heat is determined by quantum mechanical properties.

Sometimes your body will react to metal.  Like me...Sometimes my fingers turn green from my rings.  Certain food you eat makes you react to metal differently.

The skin of your fingers absorb water/ fluid and swell also.

As any sane and decent person would expect, hot water out of the tap will boil faster than cold water out of the tap. However, water that has been boiled once and allowed to cool will boil faster than hot water out of the tap. That's because boiling gets rid of the dissolved oxygen usually found in water, making it easier for the water to boil the second time around.

its an accupressure therapy for healing. One has to press particular point on palms of hand or feet to get rid of any pain. e.e. if theres a headache then you have to press few points on tip of ur thumb finger. I have read one book few years back, you can get book on this from any well established book center.
