Two 1.00 g blocks absorb 1.00 J of heat each. One block is made of gold (Au), and the other one of silver (Ag). How are the changes in their temperature ∆T(Au) and ∆T(Ag) related, and why? Cs(Au) = 0.128 J/(g·◦C), Cs(Ag) = 0.235 J/(g·◦C).
(A) ∆T(Au) = 1.84∆T(Ag) because Cs(Ag) = 1.84Cs(Au)
(B) ∆T(Au) = 1.84∆T(Ag) because Cs(Au) = 1.84Cs(Ag)
(C) ∆T(Ag) = 1.84∆T(Au) because Cs(Ag) = 1.84Cs(Au)
(D) ∆T(Ag) = 1.84∆T(Au) because Cs(Au) = 1.84Cs(Ag)
(E) ∆T(Au) = ∆T(Ag) because of the same masses and amounts of heat

5. Two 10.00 g blocks absorb 10.00 J of heat each. One block is made of lead (Pb), and the other one of copper (Cu). How are the changes in their temperature ∆T(Pb) and ∆T(Cu) related, and why? Cs(Pb) = 0.128 J/(g· ◦C), Cs(Cu) = 0.385 J/(g· ◦C). (A) ∆T(Pb) = 3.01∆T(Cu) because Cs(Cu) = 3.01Cs(Pb) (B) ∆T(Pb) = 3.01∆T(Cu) because Cs(Pb) = 3.01Cs(Cu) (C) ∆T(Cu) = 3.01∆T(Pb) because Cs(Cu) = 3.01Cs(Pb) (D) ∆T(Cu) = 3.01∆T(Pb) because Cs(Pb) = 3.01Cs(Cu)...
