  • First we need del t

[tex]\\ \sf\longmapsto Q=mc\Delta T[/tex]

[tex]\\ \sf\longmapsto \Delta T=\dfrac{Q}{mc}[/tex]

[tex]\\ \sf\longmapsto \Delta T=\dfrac{5750}{455(0.79)}[/tex]

[tex]\\ \sf\longmapsto \Delta T=\dfrac{5750}{359.45}[/tex]

[tex]\\ \sf\longmapsto \Delta T\approx 16°C[/tex]

Now

[tex]\\ \sf\longmapsto \Delta T=T_i-T_f[/tex]

[tex]\\ \sf\longmapsto T_f=T_i-\Delta T[/tex]

[tex]\\ \sf\longmapsto T_f=24-16[/tex]

[tex]\\ \sf\longmapsto T_f=4°C[/tex]
