Sand has a low heat transfer coefficient of 0.06 watts per square meter degree Celsius. This means it can retain heat for very long periods of time and explains why the sand on the beach of a hot country remains warm hours after sunset.

Sand has a much lower heat capacity than water. According to this data table, something like 0.17 to 1.00 (cal/(gram*degC)) Specific Heat of common Substances I suppose it'd be fair to summarize that answer as "It just does" though. If the abo...

Part of the reason the sand got hotter faster is because the specific heat of sand is lower than the specific heat of water. That’s why it took less light energy to change its temperature. Going Further. What other properties determine how fast a substance heats up? Try the same experiment with light and dark rock, or different types of liquids.

Which Rocks Absorb Heat the Best? ... Put the stone's capacity to store heat together with thermal conductivity to find the stone that absorbs heat the best, and does it the quickest. Mosaic marble tile floor. ... For two stone materials with the same specific heat, the denser rock will be smaller and hold the same heat energy.

WHY WE ARE NOT USING A SAND BED TO STORE THERMAL HEAT. HOW LOW CAN WE GO? When we first started thinking about designing a new house some eight years ago, I said I wanted a passive solar design and a house that was so well insulated that we could heat it with a candle.

The higher the heat capacity, the more heat it can hold. Water has a high heat capacity, higher than sand (SiO2), because it forms H-bonds, and SiO2 does not. Also, sand is particulate, breaking up the opportunity for heat to be held in by vibrational mode, whereas water is continuous.

So far my design can be simply put as 2 metal cylinders one inside the other - now I want to fill the gap with a material that has a high heat retention. the idea being that when the fire is burning (cooking food) the heat will be absorbed by this material, then once the fire is out the material will start to radiate the heat.
