its an insulator
The reason a concrete floor feels colder than a carpeted floor is because the carpet acts as an insulator to trap heat. The concrete on the other hand will stay cold way longer once it is cold.

yes
Ryan longstaf sed yes
Concrete is one of the worst insulators
no i think i am right ( i hope )
cough on someone to give them boomer remover
Glass and glass marbles are an insulator unless their is some conducting material embedded in the glass.

Concrete is not a good insulator. Concrete has a high thermal mass, which means it can store and release a lot of thermal energy (heat). This property is sometimes mistaken for insulation because it can be used to delay the transmission of thermal energy. The amount of delay is proportional to the thickness of the concrete. An example of this is the use of thick concrete walls to store thermal energy during a hot day and release it during the cooler night. For a delay of this length (half a day) the thickness of the concrete wall needs to be between 150-200mm.
Air has a higher specific heat capacity (at 1.0035 J/(g*K)) than concrete (.880 J/(g*K)).Specific heat capacity is the measure of the heat energy required to increase the temperature of a unit quantity of a substance by unit degree (Wikipedia). Because air requires more joules of energy per gram to raise it one degree Kelvin than concrete does, it is therefore a better insulator.
