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?

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.
