why cool things are sensed cold when touched?

Answer 1

You must know what heat transfer is first.

Heat transfer spontaneously takes place from a hot body to a cold body if the system is left undisturbed.

A cool object already has lower temperature than its surroundings.
Normal human body temperature is 98.5 oF
When we touch a cool object ,since we make material contact,heat transfer from our body to the object takes place.

The peripherial nerves(somatic) which transmit the signal to the brain, make us able to feel this heat transfer by the 'feeling of coolness' which takes place due to withdrawal of heat energy from the point of contact of our body.

Answer 2

You feel thing cold or hot because of the difference in temperature of yourself and the object. The larger the difference the more you feel the difference. For example if your at 1 degree and the cold object is also at 1 degree then you wont feel it cold. (though it is impossible to have a temperature of 1 degree)

Answer 3

What you actually feel is the transfer of heat from your body, not the cool of the object. Hot and cold sensations are just the transfer of heat. Hot if the heat is coming into you, cold if it is leaving you.

Answer 4

hot and cold r relative terms

Answer 5

because of the heat transalation when we touch the cool things our bodys heat flowes to cooled body thats why we feel cold.

Answer 6

itz just simple physics and some chemistry in a mixture of a weird manner..!!
in simple terms itz just the transformation of heat from ur hot blooded body is transferring into a cold and a chilled body..!!

Answer 7

cool thing has a low temp than our body. when v touch them heat from our body is transferred to that object due to latent heat transmission(every body wants to gain same temp as the body with in its contact)....so due to loos of heat v feel cool...

Answer 8

If the object is cooler than your skin, they are not in thermal equilibrium, your skin transfers heat out, and you feel cold

Answer 9

properly, I even have Anosmia (the lack of ability of the experience of scent) and you do no longer extremely get what it incredibly is like. whilst i replaced into youthful i ought to consume each and every thing yet as i've got grown older i've got replaced so as that something that i'm no longer used to is gross. lots of situations whilst i replaced right into a new child i could be eating something and then in simple terms commence throwing up.

I in all possibility have it greater handy that any one who has lost their experience of scent: I in no way had one. people who lose their experience of scent usually get very depressed. wish that facilitates.
