Why do some objects feel colder than others at room temperature?

Items that are poor conductors of heat are also referred to as insulators. A natural insulator would be a block of wood. Insulating materials will feel "warmer" than good conductors of heat, in the following example.
The opposite of insulators are good conductors of heat. An easily found good conductor of heat would be a copper pipe or iron bar.
Assuming your hand is at about 90 - 98 degrees F, and the material you are going to touch is cooler, at "room temperature" of about 70 degrees F.
If you touch a good conductor of heat (the copper pipe, a ceramic tile, a piece of steel) it will feel "cool" to the touch, as heat from your hand is transferred to the material you are touching since it is a good conductor of heat, so your hand actually is cooled down (due to the heat transfer.)
If you touch a poor conductor of heat (a block of wood, some fiberglass batting, a wool sweater) it ll feel "warm" to the touch (as compared to that copper pipe.) The reason? Since the block of wood is a poor conductor of heat, less heat is transferred from your hand to the wood...so your hand is not cooled down as much from the heat transfer as when you touched the copper pipe.
Although the wood block and the copper pipe may both have actually been 70 degrees F (room temperature), the copper will feel cooler than the wood.
The opposite is also true if the item being touched is hotter than your hand. If you touch a good conductor that is heated to 120 degrees F it will feel hotter than a poor conductor of heat (a wool sweater) that is also at 120 degrees F. The good conductor will shed heat, transfering the heat energy to your hand and creating a burning sensation. The poor conductor of heat will not transfer as much heat energy to your touch, so in comparison it will feel cooler even though it is the same temperature.

∙ 13y agowhen you feel hot,your perspiration is going out our body and the blood circulation will be faster nad if its cold you dont feel any perspiration

∙ 12y agothe answer is newton's law of cooling
some bodies can absorb heat whereas others cannot.
so we feel cold/hot

A thermometer does a fine job of measuring it.

Why do you feel cool after bath explain?
This is because your shower is usually hot. The water temperature of the shower is most likely higher or warmer than the outside temperature. Therefore your skin picks up the temperature difference between the shower and the outside temp. and then the skin picks up signals which links to your brain to tell you that it is colder on the outside. hope this helps!!!
Why is it when it's raining the water in the swimming pool is warm but when it is sunny the water in the swimming pool is cold?
It's all about how your body reacts to relative temperatures. The truth is that the pool temperature is not likely to be the culprit. It's more about how your body perceives the difference between the outside temperature vs the pool temperature. The transition from standing in the hot sun to getting into your pool makes the water feel colder than it might feel than if you are standing in cold rain before entering the pool.
How can two objects that are the same temperature feel as if they are at different temperatures?
Every substance has its nature for example water's boiling point is 100'C it wouldn't start boiling at -100'C instead it would freeze. It also depends on is that substance is a conductor or an insulator.
How would water feel if its temperature is forty degrees Celsius?
It would feel pretty hot, because 40°C=104°F, which is hot.
Can you explain why you feel warm when you are standing away from a campfire?
A fire burns fuel to produce heat and gasses. Some of the heat comes off as visible light and some warms the air in and around the fire and this rises with the smoke.However, allot of the heat comes off as infra red radiation - a form of light that you can not see with your eyes, but that you can feel with your skin (as the warmth from the fire).Your skin is always trading heat with its surroundings, your body is always losing heat at a moderate rate to the air touching it. When more heat comes in than goes out, the skin feels warm. So the side of you that faces a fire will feel hot because it is getting more heat than it is losing (because it is absorbing the infra red radiation), while your back surface is shaded from the fire's energy (by your front) and this will be losing more heat than it is receiving and will therefore feel cold.
Why do some objects feel colder than other objects of the same temperature?
The ones that feel colder, have better heat conduction.
Why do your feet feel colder when you get into a pool using second law of thermodynamics?
The basic principle here is that heat tends to flow from hotter objects to colder objects - in this case, from your feet to the cold water.
Why is mountains colder than lowlands?
Due to higher altitudes temperature decreases, so only we feel colder in mountains than low lands
Why does a soda can feel cold when you take it out of a refrigerator?
Because the temperature inside the refrigerator is colder than the temperature outside
Can a fever cause purple lips?
A fever can indirectly cause purple lips. As your body temperature rises, you start to feel colder and colder. You should have your temperature checked, any fever over 104 can cause seizures.

Birds feel colder when they are flying
Why do objects feel cold when your hand has been in hot water?
Because as your hands are warm and the object is slightly colder then it makes a big difference...
Does the blood type b make you feel colder than others?
No, blood type should not make you prone to feel cold. But Anemia can cause this.
Why does a concrete floor feel colder to you than a carpeted floor at the same temperature?
The carpet and pad are insulating you from the concrete floor.
Could the blood type b make you feel colder than others?
No, blood type should not make you prone to feel cold. But Anemia can cause this.
How does the temperature of the air affect the amount of humidity that you feel How does the air's temperature also influence the form of precipitation that falls?
The higher the temperature of the air the higher the amount of humidity you feel. Also the colder the airs temperature it can cause precipitation such as hail, snow, and sleet rather then just rain.
What are some differences the air at sea level and the air at the top of a mountain?
At the top of the mountain you feel more colder than the normal temperature.
