Statement 1: On throwing aluminium powder in air, it catches fire.

Statement 2: $2\mathrm{Al}+\frac{3}{2}{\mathrm{O}}_2\text{\hspace{0.17em}\hspace{0.17em}→\hspace{0.17em}\hspace{0.17em}}{\mathrm{Al}}_2{\mathrm{O}}_3;\mathrm{\Delta H}=-\mathrm{ve}.$

The reaction is highly exothermic and once started continues to develop fire.
