Mass-weighted gas phase diagrams for the high-resolution galaxies averaged over the snapshots from t = 300 Myr to t = 1000 Myr with a time interval of 10 Myr. The red dashed curves represent the median temperature within each density bin. The grey curves are the equilibrium temperature assuming G₀ = 0.01, 0.1, and 0.00324 for 0.02 Z_⊙/full, 0.2 Z_⊙/full, and 0.02 Z_⊙/noRT, respectively.
