A systematics of thermal properties, for nuclei with 16≤A≤30, is presented. The study has been motivated by previous reports on phase transitions involving nuclei belonging to the 2s-1d shell. We have used the nuclear SU3 scheme to calculate the specific heat and the temperature dependence of the intrinsic quadrupole moment for each nuclei. We have found that finite size effects and not true phase transitions are affecting the temperature dependence of these quantities, at least within the SU3 scheme and for the nuclei which we have considered.
