entropy

you are your own system (your body)...while the environment around you is another and the object you touch is yet another.

When you touch that object, you are changing your entropy when you made contact.

Of course your body is warm and works at a certain body temp and any deviation from it will be felt by your nerves in your fingers, because they operate at an optimal 36.X degrees Celsius or so.

So is entropy the transfer of heat from my body to the object I touch?
Or is it a measure of heat that remains within my body after I touch the object?

all your doing is passing heat from yourself to a object.

Definition of ENTROPY

1
: a measure of the unavailable energy in a closed thermodynamic system that is also usually considered to be a measure of the system's disorder, that is a property of the system's state, and that varies directly with any reversible change in heat in the system and inversely with the temperature of the system; broadly : the degree of disorder or uncertainty in a system
2
a : the degradation of the matter and energy in the universe to an ultimate state of inert uniformity
b : a process of degradation or running down or a trend to disorder
3
: chaos, disorganization, randomness

i hope this clears things up for you.
