This question studdenly appeared in my mind, A hypothetical liquid that is completely incapable of transferring (consequentially holding too, right?) Any heat in any way, how would it feel to touch it? We feel cold when heat gets out of our body and hot when it gets in right? Would it just feel perfectly neutral?

I can only partially answer this. Humans cannot sense moisture on the skin, only temperature and tactile (e.g. something on the skin, or moving along the skin like a droplet)

Something that cannot transfer heat would, I assume, feel not like putting a hand in water, but rather something....else?

Like putting your hand in a vacuum chamber, probably.

Oh yeah, that'd make sense

You don't feel a temperature. You feel an energy/heat transfer.

When you touch something cold, it's cold because when you touch it, there is a transfert of heat from your hands to the cold object.

If you touch something hot, it's hot because there is a transfer of heat from the object to your hands.

In a hot room, it's a transfer of heat from the air to you.

But there is something more too.

You generate heat. If you were in a room with exactly the temperature of your skin, it will feel hot, because the heat you generate cannot dissipate in the air.

Now let's say you touch the liquid which has no energy transfer capabilities. In such way, well, you wouldn't be able to touch it.

But say we could. Your hands won't feel immediately any heat/cold because there cannot be any energy/heat transfer. However, as you generate heat, your hands will start to get hotter and hotter has the heat cannot be dissipated around, even if your body will try to compensate though other parts of the body. It's like putting your hands in a glove.

Thank you!
