The answer to your question is Q = 1432 Joules

Explanation:

Data

mass of Al = m = 40.0 g

temperature 1 = T1 = 50°C

temperature 2 = T2 = 90°C

Specific heat = C = 0.895 J/g°C

heat = Q = ?

Process

1. - Write the formula to calculate heat

Q = mC (T2 - T1)

2. - Substitution

Q = 40 (0.895) (90 - 50)

3. - Simplification

Q = 40 (0.895) (40)

4. - Result

Q = 1432 Joules
