Abstract: Thermal pressure is an important physical quantity playing the central role in the evaluation of high temperature equations of state for solids. Recently, Kumar and Singh, [Indian J Phys, 78 (2004) 1225] have studied several formulations for the temperature dependence of thermal pressure demonstrating the inadequacies of the models developed by earlier researchers. It is emphasized in the present work that the method adopted by Kumar and Singh is seriously flawed and inconsistent with the recent findings. The Suzuki formulation for volume thermal expansion has been derived correctly in the present study and found to be in close agreement with the experimental data on thermal pressure for various solids considered by Kumar and Singh.
