Which has a higher specific heat, water or sand ... 

Was this your answer As suggested by the illustration, the temperature of water increases less than the temperature of sand in the same sunlight. Water therefore has the higher specific heat.Those who visit the beach frequently know that beach sand quickly turns hot on a sunny day while the water remains relatively cool. At night, however, the sand feels quite cool while the water s temperature feels about the same as it was during the day...

The apparent density of the coated sand was p = 1394 kg m-3, the specific heat was cp =695 J kg-1 K 1, and the thermal conductivity exhibited the following variation with temperature ... 

Specific Heat—The specific heat of particles is determined by heating a given weight of a sample to nearly 100 deg C in a steam bath, and quickly stirring the hot particles into the water in a calorimeter. The temperature rise may thus be determined and the specific heat obtained from this observation and the known masses involved. Most soils, whether loams, sands, or clays, have specific heats ranging from 0.15 to 0.20 cal per g per deg C.

Two major applications of DSC techniques for the study of coals, oil shales and oil sands have been identified, namely resource evaluation (i.e., assay and proximate analyses) and specific heat determinations. The information content from DSC is much enhanced when TG is also used. The method of sample containment and choice of experimental variables are critical in the study of these materials. 

On a hot day, the beach sand gets hot but the water stays cool. Would you predict that the specific heat of sand is higher or lower than that of water Explain. (3.5)... 

You can see the difference when walking in bare feet on a sandy beach on a hot day. The specific heat of sand is about 20 percent that of water, so the sand warms up considerably (sometimes to the point of discomfort ), while the temperature of the water is cooler and very pleasant. 

In the table m, 0 and c denote the mass, temperatme and mass-specific heat capacity, respectively, of the constituent materials. With the given subscripts, the mass of sand is denoted m, temperatme of cement is denoted Oc, etc. 

The same amount of heat causes a greater temperature change in the sand than in the water, thus the sand must have a lower specific heat than that of water.
