How would be the feeling of putting your hand inside a liquid that's 100% incapable of transferring heat? (self.asklemmy)

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 would assume you'd feel the temperature, though your hand would not change the liquids temperature. Think about walking into a hot room, you feel the heat.

If you were drifting through the vacuum of space without a spacesuit, would you not freeze? Not sure if this comparison works though.

This wouldn't happen because 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.

Also remove your other duplicate comments.

It feels cold in space? Thought the thing there was more bout the lack of pressure and things like that
