The evolution of ultracold plasmas by measuring electron temeprature was analyzed. It was observed that competition between heating and cooling mechanisms drives electron temperature to a value within narrow range, shortly after plasma formation. Significant cooling was observed when initial kinetic energy of electron was large and significant heating was also observed when low initial kinetic energies were imparted. The results show that electron components of ultracold plasma were never observed to be in strongly coupled regime.
