Why does marble etc stay cold to the touch, even when it is in a warm environement?
October 28th, 2009 | by admin |My living room table top is marble, and I’ve often wondered why it remains cold–does that mean stone buildings are cold?
Marble has a higher specific conductance than the air which means it can obtain heat or cold better. Air temperatures can change quickly but materials with higher conductance take longer to change.
You will notice on a hot summer day after the sun goes down, the pavement will still be very warm even if the air has cooled signifcantly. Your table is just on a smaller scale.

It absorbs heat, same thing with water, but in the case of water, when it absorbs heat it turns into a vapor. By absorbing heat from you it makes you feel cold, because basically heat is being sucked out of you.
