Percentage distributions of cold-gas (T<10⁵ K in upper row panels), warm-gas (10⁵≤T<10⁷ K in upper-center row panels), hot-gas (T≥10⁷ K in bottom-center row panels) and all-gas (in bottom row panels) masses considering the baryonic masses. The histograms are divided in the haloes with ${log}_{10}\left(M_{500\mathrm{c}}/{\mathrm{M}}_{\odot }\right)<14$ (left colum panels), ${log}_{10}\left(M_{500\mathrm{c}}/{\mathrm{M}}_{\odot }\right)\ge 14$ (center colum panels) and all halo (right colum panels) masses. (Black histograms) TNG100 haloes. (Red histograms) TNG300 haloes. The dashed lines represent the normal distribution fitted in their respective histogram (with their respective colour).
