Thermal convection in a horizontal fluid layer induced by internal heat generation is investigated experimentally. Thermo-chromic Liquid Crystal (TLC) is used to visualize the temperature field in the fluid layer. Color component of TLC is calibrated and the visualized image is converted to the temperature field. Temperature field for each Rayleigh number determines the convection cell dilatation with respect to the Rayleigh number. Deformation of the cell with increasing the Rayleigh number is shown by the temperature profile in a cell. The critical Rayleigh number at onset of convection is estimated by using a variation of temperature difference in a cell.
