Question

The specific heat of aluminum is 0.900 j/g•°

c. how much heat is required to raise the temperature of a 30.0 g block of aluminum from 25.0°c to 75.0°c?

Answer 1

To determine the heat required to raise a body's termperature by a certain number of degrees C, we use the equation,
H = mcpdT
where m is mass, cp is specific heat, and dT is the temperature difference. Substituting the known values,
H = (30.0 g)(0.90 J/gC)(75 - 25)
H = 1350 J
Thus, there is a need for 1350 J of heat for the process.
