Abstract
The thermal conductivity (k) and the specific heat capacity (C) of some samples collected from three major landforms in Akwa Ibom State, Nigeria; namely Beach Ridge Sand (BRS), Coastal Plane Sand (CPS), Sandstone/Shale Hill Ridges (SHR) were measured. Results show that an increase in C of SHR and BRS samples taken from different locations gives rise to decrease in k. The C of the area under study falls within the range 1813.64 Jkg-1K-1 to 3313.24 Jkg-1k-1 while the soil thermal conductivity was between the range 0.272 Wm-1K-1 to 0.451 Wm-1K-1. The C of the soil samples has great effect on crop and construction works
Keywords: Thermal conductivity, specific heat capacity, soil and sand.
