Question

How much heat is required to raise the temperature of 40.0 g of aluminum from 50.0 degrees C to 90.0 degrees C? The specific heat of aluminum is 0.895 joules per gram C

Answer 1

The answer to your question is Q = 1432 Joules

Step-by-step 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
