Is it true that marble always remains 8 degrees cooler than room temperature?

Question

I have heard on the grapevine that marble always remains cooler than room temperature. Could someone explain if this is just a myth or fact?

Answer 1

yes it is cooler.

Answer 2

If you have a piece of marble surrounded on all sides by air at 25 Celsius, thermodynamics dictates that after enough time, it must come into thermodynamic equilibrium with the air (it will be the same temperature as the air).

However, marble is often placed on the ground, and is a good conductor of heat. So, if the ground is cooler than the air, it is quite possible for the marble to remain cooler than the air. However, it will always be warmer than the ground in this case.

Answer 3

No, that would violate the First and Second Law of Thermodynamics.

Everything eventually reaches thermal equilibrium with its environment unless it has a way of producing its own heat. So a cold rock will eventually gain enough heat from the air that it will eventually become the same temperature as the air.

Marble may FEEL colder to you than the air simply because it is more efficient at absorbing heat from your body (which IS warmer than room temperature, by-the-way, since you make your own heat), but that is different than saying that the marble is colder than the air -- which it is not.

Answer 4

marble is a hard metaphoric stone and is always cooler than the room temperature and thus widely used in warmer countries to make floors and walls
to harness the coolness
and create a comfortable living environment
it does this because it isa great insulator and doesnt hold on to the heat
in some countries they have cold flowing water undervthe floors made of marble to make it even cooler

Answer 5

No, stone takes a long time to either heat up or cool down. They use stone in storage heaters, as once the stone has heated up (overnight at cheaper rates - part of the point of the exercises), it then releases its heat very slowly - this is basically because stone is a poor conductor of heat, but this poor conduction can be very useful.

Marble is particularly useful because it is a dense stone, and therefore one of the poorest conductors of heat, and by the time it becomes warm, the sun is starting to go down. Try by putting a thermometer on marble once in the morning and one later in the day and see.

Answer 6

No, its thermal conductivity is high, so it draws heat quickly from your body when you touch it and you feel cold. It's like wind chill; you feel colder than the surrounding air because of the wind.

Answer 7

I am a brick mason and yes marble ,granite and other types of stone remain cool in the summer and help to hold the heat in the winter

Answer 8

myth. Look up the zero th law of thermodynamics
