It is necessary to determine the specific heat of an unknown object.The mass of the object is measured to be 199.0 g.It is determined experimentally that it takes 16.0 J to raise the temperature 10.0°C.Find the specific heat of the object. A) 8.04 J/kg • K B) 1600 J/kg • K C) 0.00120 J/kg • K D) 3.18 × 10⁶ J/kg • K

We can use the formula Q = mcΔT, where Q is the amount of heat transferred, m is the mass of the object, c is the specific heat capacity, and ΔT is the change in temperature. Rearranging the formula, we get c = Q/(mΔT). Substituting the given values, we get c = 16.0 J/(199.0 g * 10.0°C) ≈ 8.04 J/kg • K. Therefore, the best choice is A).
