ELI5: Why do stone and marble counters feel cold to the touch? They have been in the same temperature as the rest of our house for hours, and yet they are significantly colder.

The marble has a higher thermal conductivity than the other objects at the same temperature. This means when you’re in contact with the marble you lose your heat at a faster rate than you would if you were in contact with a material with a lower thermal conductivity.
