Abstract : A Steady state method is used for the measurement of specific heat of Rajasthan desert sand as a function of temperature. The measured values of specific heat vary from 0.194 Cal/gm/degree calcius(at280 degree K) to 0.239 cal/gm/degree calcius(at 500 degree K).A curve of the form C=A+BT is found to follow the experimental data. a nomogram is also drawn to estimate the effective specific heat of porous materials from the knowledge of specific heats of constituents and mass porosity.
