Metal is a better conductor of heat than wood, so when you touch a metal object at room temperature, it conducts heat away from your skin more effectively than a wood object. This rapid transfer of heat creates the sensation of the metal feeling cooler even though both the metal and wood objects are at the same room temperature.
What else can I help you with?
Which metal feel coldest at same room temperature?
Metals seem cooler to the touch because our perception of the temperature is governed by both the actual temperature, as well as the thermal conductivity of the metal. And if the metal also has a high thermal capacity, this feature will delay the metal from approaching the real temperature.The temperature we are sensing is of course how close to body temperature the metal is.As to which metal, the combination of thermal conductivity and thermal capacity will feel coldest. Probably silver or copper.
Is heat energy transferred from a warmer object to a cooler object?
No, heat ALWAYS travels from hot to cold. It is not actual heat moving, it is energy. The more energy something has, the warmer it feels. For example, when you touch a metal railing on a winter day, it feels cold. That is because your hand has more energy than the rail. The energy from your hand is traveling into the railing to equalize the energy (moving towards equilibrium. The loss of energy in your hand is what gives you the "cold" feeling. Heat/energy NEVER moves from cold to hot.
Why do metals feel colder than wood when in same temperature and conditions?
Actually, the reasons metal objects often feel cooler than wooden objects has to do with the way the body feels heat and the rate metal conducts heat. If a room is left at 72 degrees Fahrenheit, all of the objects in the room will eventually reach 72 degrees, but a person standing in the same room will be at 98.6 degrees. When a person touches something in the room, he or she will be at a higher temperature than the object. Heat will flow from the hotter object (the wood or metal). The heat will flow through the wood or metal away from the person's skin, but at different rates, faster through the metal and slower through wood. We say then that metal conducts heat better than wood does. The end effect is there is less heat left in the finger where it touches metal than where it touches wood. The nerves in the finger sense the finger is cooler and the metal object seems cooler.
Why heat transfer to metal objects?
Heat transfers to, and from, any object, not just metal object. Metals in general are very good conductors of heat; as a result, you might feel the temperature more easily when you touch a metal object. If you get burned more easily by a metal object than by a wooden object, for example, both at the same temperature, this is a direct result of heat conduction.
How does a thermometer work?
A thermometer works by measuring the temperature of an object or environment using a liquid or metal that expands or contracts with changes in temperature. This causes the level of the liquid or the length of the metal to change, which is then converted into a temperature reading on a scale.
How do you know an object is a metal?
it usuly feels colder than plastic

Why does your body detects metal as an cold object?
Because metals are usually good conductors of heat. When you touch metal at a spot that's cooler than your skin, the bit of heat that flows from your finger to the metal at that spot quickly flows onward to cooler parts of the metal ... leaving that spot still cool, and still taking heat out of your finger. If you waited around until the entire piece of metal warmed to the temperature of your skin, then the metal wouldn't feel cool any longer.
Why does a metal door knob feel cooler to your hand than a carpet feels to your bare feet?
Metal can conduct heat away from your body (hands) faster than carpet.

Why does metal feel cooler to the touch than wood?
Metal conducts heat better than wood, so when you touch a metal object, it can quickly draw the heat away from your skin, making it feel cooler. Wood is a poor conductor of heat, so it doesn't transfer heat as efficiently, leading to a different sensation when touched.
Is the metal object really colder than the piece of wood at the same room temperature?
Yes, absolutely.
Who would win imperfect cell or metal cooler?
metal cooler would win as Cell he is in one of his weakest form.
Why does a plastic fizzy drink bottle usually feel warmer than a metal can of drink even if they are at the same tmeperature?
The plastic drink bottle feels warmer than a metal can because the metal can has a higher thermal conductivity compared to the plastic drink bottle. Thermal conductivity is the property of a substance to conduct heat, and the metal can, being made of metal, has a much higher ability to conduct heat compared with the plastic bottle. This means that when you touch the metal can, it draws out your own body heat faster than than when you touch the plastic bottle, so the can feels cooler.
