The answer can be determined using the equation Q = mC_p ΔT. Using the given scenario with Q = 1000 J, m = 3 kg, and ΔT = 50 deg C. The heat capacity, C_p, of the object can be determined. The C_p is equal to 6.6667 J / (deg C kg). The calculated amount of heat needed for each option is A. 2000 J, B. 1000 J, C. 4000 J. D. 2000 J. Thus, the two situations that require the same amount of heat to be added are choices A and C.
