Why does a metal object feel colder to touch than a non- metal object?

Question

please help with my homework!!!!!! thank you

Answer 1

When you touch something at ‘room temperature’, your body-heat is warming the object. Heat is flowing from your hand into the object (assuming your hands’ temperature is greater than that of the object).

Metals are good conductors of heat. If you locally heat a certain spot on a piece of metal, the heat will be conducted away from that spot and dissipated across the entire object. If it was a perfect conductor of heat, the temperature of the entire object would rise uniformly and no one spot would have a higher temperature than another spot. So as soon as you rise the temperature of one spot on the metal, the heat is conducted around the whole object and the overall rise in temperature is much less (since that same amount of heat must go into raising the entire object’s temperature and not just some local area).
So the metal helps move heat around so that the temperature difference between you and it will be larger and more energy will flow into it.

We will lump Non-metals into a group called non-conductors / insulators (even though I am not saying that all non-metals are poor conductors).
Non-conductors do not conduct heat very well. Thus, you can raise the temperature of the object locally at a specific spot without the temperature elsewhere changing a great deal. So when you touch a certain area, you heat it up more quickly since you no longer need to heat up the entire object to raise the temperature of the entire object. Less heat needs to flow out of you before the spot you touch becomes the temperature of you hand.

If we sense things as ‘hot’ or ‘cold’ by the direction of the flow of heat energy, it might seem that conductors feel colder than insulators if you touch them due to how much and how long heat flows out of / into our hand.

Answer 2

Firstly, you need to understand that the cold feeling is caused by the passage of heat (energy) from your body to another object. Second, different materials have different heat conduction properties. For example, metal has a high conductivity to heat whereas wood has poor (and that is why we can use a wooden spoon to cook and it won´t get hot). So, hold a metal object with your right hand and a wooden object with your left hand. Although both objects are at the same temperature, you feel the metal object as colder because the heat (energy) from your hand passes to the metal object faster than to the wooden object.

Answer 3

metallic feels less warm to touch for 2 distinctive motives. the 1st reason has to do with particular warmth. particular warmth is the quantity of warmth that must be further to a substance to advance a definite volume of that substance to a definite temperature. that's proper to the question as a results of fact brick has a larger particular warmth than maximum metals including iron and metallic. If a a million pound brick and a a million pound metallic bar are placed in an oven, the metallic will take up the warmth speedier than the brick will. on the comparable time, if positioned exterior on a cold day, that comparable metallic bar will lose warmth at a speedier p.c.. than the brick will meaning the metallic actually is less warm. the 2d reason is plenty easier and has to do with the feel of maximum metals vs the feel of a brick. If we use the metallic bar occasion back, a metallic bar is going to have an fairly delicate floor so once you touch it your dermis is contacting the bar in extra places. once you touch a brick, the brick has a gritty texture and the exterior is choppy so the brick in simple terms contacts your dermis at specific factors. The extra factors at which your dermis contacts a cold merchandise, the extra nerves deliver the sensation of chilly on your strategies and consequently the metallic feels less warm whether they are the comparable temperature.

Answer 4

metal can dissipate heat a lot quicker than non - metal objects. So it is not uncommon for a metal object to be hot and moments later to be cool to the touch, while other objects will retain their heat longer.

Answer 5

Metallic oblects are good cxonductors of heat and therefore draw away heat quickly from the skin if it is at a higher temperature than the metal.

Answer 6

Metal is a poor conductor of heat and warms more slowly in your hand than other objects.

Answer 7

metal is a conducter
