Why is it that some materials, ex: metal spoon, feel colder than others, ex: paper even though they are the same temperature?
In: Physics
Unless things are the same temperature as your hand they will feel cooler or warmer when you touch them. Some things like metal are thermal conductors and can transfer heat quickly. Some like cork or wood are thermal insulators and can only transfer heat slowly. If two cold things are the same temperature, the one that can transfer heat quickly will feel colder than the one that can transfer heat slowly. So a cold steel spoon will feel colder than a cold wooden spoon at the same temperature.
Basically because those materials (ex: metal and paper) have different heat conductivity rates.
Metal conducts heat better, so when u touch the spoon it disperses heat from your hand quicker onto the spoon and gives you a cold sensation. The paper does this poorly so you just feel the “normal” temp on your hand. Sorry for bad english.
The temperature of all objects in a room is the same pretty much, you just feel the difference in conductivity as it conducts heat away or towards your hand
Hot/cold feeling is based on how quickly it transfers heat to/from your body. Metals have a high heat transfer rate, so anything made of metal feels colder than air, even though both metal and air at the same temperature.
* Humans sense heat and cold based on heat transfer in or out of their body.
* When you pick up a snowball and it feels *very* cold, it’s because a lot of heat is being sucked out of your hand.
* When you grab a hot steering wheel in your car in the summer time, it feels hot because a lot of heat is being pushed into your hand.
* Some materials are better at conducting heat than others.
* When you touch them heat transfers faster than another object so you feel that temperature more intensely.
