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. 

The correct answer would be 1. precipitation
