Lets say room temp is 75 degrees. Your body temp is around 98 degrees. metal conducts heat very well so when you touch it all the heat is transferred to the metal whereas wood is more insulating and the heat from your finger leaves at a much slower rate. Also, there is also a difference in emissivity between the two materials. They radiate energy differently. The metal object not only feels colder in the room (or hotter in the sun), it really is a different temperature. Wiki/Google "emissivity."
Metal is a thermal conductor and Wood is a thermal insulator. When you touch the metal, the energy transfers rapidly to the metal, making it colder. When you touch the wood, the energy transfers very slowly from your hand to the wood.
Metal is a good conductor of heat, so it can quickly transfer heat away from your skin, making it feel colder. Wood, on the other hand, is a poor conductor of heat, so it does not draw heat away from your skin as efficiently, resulting in a less intense sensation of coldness.
metal conducts heat very well so when you touch it all the heat is transferred from your hand to the metal whereas wood is more insulating and the heat from your finger leaves at a much slower rate. this makes it so that the wood feels warmer than the metal when the two substances are touched at the same temperature. Also, there is also a difference in emissivity between the two materials. They radiate energy differently. The metal object not only feels colder in the room (or hotter in the sun), it really is a different temperature.(emissivity-The ratio of the radiation emitted by a surface to the radiation emitted by a blackbody at the same temperature.)
Metal conducts heat faster than wood. Thus is you pick up a piece of wood in one hand and a piece of metal in the other the metal will take heat away form your hand faster than the wood and thus feels colder.

What is the metal piece that holds the bulb in place?
The metal piece that holds the bulb in place is called a socket. It provides electrical contact to the bulb and secures it in position within the light fixture.
Does a flat piece of metal have air trapped within its sides?
No, a flat piece of metal does not have air trapped within its sides. Metal is a solid material that does not contain air pockets unless intentionally added during manufacturing processes like casting or forging.
What the metal part of pencil called?
The metal part of a pencil is called a ferrule.
Do pencil have metal?
Yes, pencils typically have a thin metal piece called a ferrule that holds the eraser in place. Additionally, some mechanical pencils have a metal tip that dispenses the lead as it is used.
What is the metal piece at the end of a pencil called?
The part that holds the eraser on is called "ferrule" and the part you write with is normally graphite, but sometimes is lead or charcoal.
Why a metal feels colder to touch than wood kept in a cold place?
Metal is a thermal conductor and wood is a thermal insulator.when you touch the metal the energy transfer rapidlyto the metal,making it colder.when you touch the wood the energy transfer very slowly from your hand to the wood kept in a cold place.

My passenger side window in a 1997 Saturn will not roll down?
More than likely the piece of metal holding the gears aligned is bent. You can remove the outer panel and hammer the metal piece back in place.
What is the metal piece that fasten the handle to the tang?
The metal piece that fastens the handle to the tang is called a rivet. Rivets are permanent mechanical fasteners that hold the handle securely in place on the blade of a knife or tool.
Does chewing JuicyFruit make mouth temperature warmer or colder?
the truth is of course it makes it colder the chemical reactiion taking place is mainly the fact that when you breath in it feels warmer. SO obviously makes your mouth grow colder. My research & experiments as a scientist have shown so much your welcome for helping you rediscover the answer for you. Scientist Liane

How do you drill a hole in a bathtub?

What is the plastic piece hanging under 2002 Mercury Villager?
You are probably referring to the piece under the front bumper. That is a stone shield. It is held in place by several plastic rivets and metal screws.
