Celine Posted July 14, 2005 Share Posted July 14, 2005 I am trying to find out what the smallest difference in temperature is that a person can possible sense by touching objects.... Any answers, hints.. Link to comment Share on other sites More sharing options...
swansont Posted July 14, 2005 Share Posted July 14, 2005 Your body is much more sensitive at detecting the flow of heat rather than temperature differences, which is why a piece of metal will feel cool while a peice of wood will not, when they are both at e.g. room temperature. The metal has a higher thermal conductivity. So, given that, your question is not defined well enough to give a definitive answer. Link to comment Share on other sites More sharing options...
Celine Posted July 14, 2005 Author Share Posted July 14, 2005 ok ++++ Thanks for that, I can define my question a bit more>> I am trying to find out, what a difference someone can perceive when he is given a number of plates with different temperatures. What should the difference be of the warmth? Or in other words> If someone would have a PERFECT perception of temperature with his hands, what would be the smallest difference that is humanly perceivable? If I give him a plate that is 25 degrees, then one that is 25.5, can he feel the difference? I need to know, in degrees, what is the smallest amount that is possible perceivable by a person touching an object.... *I am sure someome has figured this out....* Link to comment Share on other sites More sharing options...
