We performed a systematic study of the Doppler shifts and electron densities measured in an EUV bright point ( hereafter BP ) observed in more than 10 EUV lines with formation temperatures from \log ( T / K ) = 4.5 to 6.3 .
Those parts of a BP seen in transition region and coronal lines are defined as its cool and hot components , respectively .
We find that the transition from cool to hot occurs at a temperature around \log ( T / K ) = 5.7 .
The two components of the BP reveal a totally different orientation and Doppler-shift pattern , which might result from a twist of the associated magnetic loop system .
The analysis of magnetic-field evolution and topology seems to favour a two-stage heating process , in which magnetic cancelation and separator reconnection are powering , respectively , the cool and hot components of the BP .
We also found that the electron densities of both components of the BP are higher than those of the surrounding quiet Sun , and comparable to or smaller than active-region densities .
