temperature is the degree of hotness and coldness of a body. It is directly proportional to the

Answer:
When we touch something, we dont really register its temperature directly.
What we sense is actually heat flow. Our sensors can only register their own temperature (not the object we are touching) and so they notice if they are getting hotter or colder, and make inferences from that.
For some materials, like wood, or cotton batting, or wool, heat doesn't flow very fast. When we touch it, the part right against our skin warms up to skin temperature very quickly, but then little else happens. That heat does not flow through the whole object very fast.
But steel, or stone will conduct heat very rapidly. When I touch it, the part next to my skin starts warming up to skin temperature. But almost immediately, that heat moves into the rest of the block, heating up that entire block. And so the part next to my skin is still cooler than the skin, and more heat flows out of me, as the two objects (me and the steel) try to reach an equal temperature.
In effect, I will loose heat (and thus feel cool) until that entire piece of steel is at my skin temperature.
We judge temperature by how fast our own heat flows into it, by how fast it makes us cold (or hot). It is the flow of heat we are sensing.
It is analogous to the temperature of that object, but not exactly the same
