re: which material absorbs heat most efficiently sand
2. the rate at which heat is absorbed. the first is a matter of heat capacity and to answer this you must either measure or look up the heat capacity of the materials in question. the second however is much more complex. it depends not only on the heat capacity but the the heat transfer coefficient and whether or not the material is porous.

specific heat of water vs. specific heat of sand | science
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.
