plasma component.

Figures \[fig:temp\_A\], \[fig:temp\_B\], and  \[fig:temp\_top\] show the time evolution of peak values of DEMs obtained at different temperature components (top panels) and associated temperatures (bottom panels) obtained at ARTBs A, B, and at the loop-top, respectively. The color of the curves shown in Figures \[fig:temp\_A\], \[fig:temp\_B\] and  \[fig:temp\_top\] are same as those for Gaussians shown in Figure \[fig:aia\_dem\]. These curves again reveal the existence of background cool and warm plasma components throughout the time evolution of the ARTB A and B as well as the loop-top. The emission measure from warm plasma component is higher than that from cool plasma throughout the evolution. The contribution from hot plasma component due to temperature $\approx 10^{6.7}-10^{7.2}$ K appears only during the ARTB and later in the associated loop. The temperature of hot component of the plasma changes with time. In the beginning, at the ARTBs, the plasma heats up to a temperature of $\approx 10^{7.11}$ K at 13:04:07 UT and later drops continuously afterward and reaches a temperature of $\approx 10^{6.64}$ K after about 6 minutes. The plasma at the loop-top heats up to the temperature of $\approx 10^{7.06}$ K at time 13:04:07 UT and decreases to $\approx 10^{6.87}$ K
