Respuesta:

5.4927 * 10 ^ 4 J

Explicación:

Dado que :

Capacidad calorífica específica del aluminio, C = 0,9 J / g. C °

Temperatura inicial, t1 = 22,8 ° C

Temperatura final, t2 = 94,6 ° C

Masa de aluminio, m = 8.5 * 10 ^ 2 g

Usando la relación:

Q = mcΔt

Δt = t2 - t1 = 94,6 - 22,8 = 71,8 ° C

Q = cantidad de energía térmica requerida

Q = 8.5 * 10 ^ 2 * 0.9 * 71.8

Q = 549,27 * 10 ^ 2 J

Q = 5,4927 * 10 ^ 4 J
