Equal mass samples of gold and aluminum (at the same initial temperature) absorb 200 J of heat. If the sample of aluminum reaches a lower final temperature than the sample of gold does, what is then true? A. Aluminum has a lower specific heat than gold – less heat is required to raise the temperature of the aluminum sample. B. Aluminum has a higher specific heat than gold – less heat is required to raise the temperature of the aluminum sample. C. Gold has a lower specific heat than aluminum – less heat is required to raise the temperature of the gold sample. D. Gold has a higher specific heat than aluminum – less heat is required to raise the temperature of the gold sample.
Expert Answer
Answer
Q = m*C*(Tf-Ti)
C and (Tf-Ti) are inversely related
Tf-Ti is less for Aluminium than gold
So, C must be more for Aluminium than gold
Answer: option C
