At zero temperature SU(2) and SU(3) gauge theories confine quarks and spontaneously break chiral symmetry. At some non-zero temperatures T/sub c/(T/sub F/) these gauge theories lose confinement (chiral-symmetry breaking). We have studied the order of these phase transitions and the relation between T/sub c/ and T/sub F/ using simulation methods which neglect internal fermion loops. For SU(2) both transitions are second order and 1 less than or equal to T/sub F//T/sub c/ < 1.30. For SU(3) the transitions are first order and we find 1 less than or equal to T/sub F//T/sub c/ less than or equal to 1.05, with T/sub c/ approx. = 200 MeV.
