Why is a concrete floor colder than carpet even though they are the same temperature?

Concrete conducts heat away from your foot faster than carpet, so it feels colder, but they are the same temperature.

Why a metal handrail feels colder than a wooden handrail even though they are at the same temperature?
The metal has higher thermal conductivity than wood so it takes heat away faster from your warm hand, causing it to feel cold
Why does a piece of iron feel colder than a piece of wood even though they are both in the same temperature?
Wood is a porous material in which a lot of air is trapped, and as a result, it is a poor conductor of heat. Iron is a denser material which is a good conductor of heat. So when you touch iron, heat flows easily from your finger into the colder piece of iron. Heat flows much more slowly from your finger into a piece of wood, even if the wood is exactly the same temperature as the iron.
Do cold or normal magnets have more power?
Most materials which exhibit a spontaneous magnetisation (ie a lump of it can act as a magnet without you doing anything) lose this property above a certain temperature. However, if you're reasonably far below this temperature, as iron is at room temperature, making it colder probably won't make much difference (though at extremely low temperatures all kinds of odd thing can happen). The most powerful magnetic fields used at the moment though are not generated by a magnetic material, but by running a current through a superconducting coil. In order for all known materials to superconduct, they do have to be cooled to a very low temperature.
To what temperature can a window air conditioner cool your room?
It depends on the BTU of the air coditioner, the cubic footage of space in the room to be cooled, and the temperature and humidity in the room. Under best conditions, an standard air conditioner can only cool a room to the mid 60's. Any colder than this causes the evaporator to ice over, clogging the air flow into the room, which causes the temperature to rise, even though the air conditioner is still running.
Why does the tiled floor feel colder than a rug even though they are at the same temperature?
Tile is smooth getting a large contact area.A rug contains lots of air pockets, acting as thermal insulators.This allows cool tile to conduct heat away much faster than a cool rug.If they were both warmer than body temperature the tile would feel warmer for the same reason.
Is mars one of the warmer or colder planets?
WARMER. Comment: It's not very warm though. The average temperature is well below zero degrees Celsius.
What does falling of his mercury mean?
It's most likely to relate to thermometers, as mercury in them will drop when the temperature drops due to the expansion and contraction of matter. Nowadays thermometers have pure alcohol in them though. Hope this helps.
When pressure decreases what happened to the volumes?
There are three inter-related effects, Pressure, Volume, and Temperature. If you partly evacuated a sealed container, then it would get colder, even though the volume was constant.
Does air need to be a certain temperature for plants to use carbon dioxide?
All living processes is pure chemistry. The colder it gets, the longer time it will take to make chemicals react. There is of course a limit as to how cold a plant can become before simply dieing. Plants in the colder areas of earth grow slower. I do not know the "theoretical" lowest temperature though.
Why heavy clothing makes one feel comfortable during cold nights?
Why does ice seem much colder to the teeth than ice water; even though they may be out the same temperature
Is ice always at 0?
Assuming you're talking centigrade here... No, if the ambient temperature is lower then the ice will be colder too. It can't be more than zero degrees though, because then it will melt.
How fast will liquid nitrogen freeze lead?
The regular definition of freezing something is when its turning it from liquid to solid, and since lead at room temperature alread is a solid it can't really be frozen. It can get colder though.
How fast will liquid nitrogen freeze copper?
The regular definition of freezing something is when its turning it from liquid to solid, and since copper at room temperature alread is a solid it can't really be frozen. It can get colder though.
Does temperature change due to humidity change?
No, but they are both determined by the same factor: geography. It may make it feel a little warmer or colder though, just like wind chill, but it doesn't actually change it.
Muratic acid and discoloring of concrete?
muriatic acid should not cause discolouration to concrete it will eat it away though.
Which planets are hotter than the Earth?
All eight planets have a surface temperature, though it varies as the planets distance from the sun varies. Closer planets to the sun generally have a higher surface temperature, while further planets have a colder surface temperature.
Can lightning travel though concrete?
Not that i have ever seen so no
