Measurement of Thermal Conductivity and SpecificHeat Capacity of Three Major GeomorphologicalUnits in Akwa Ibom State, Nigeria

摘要

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.
