If two objects are given the same amount of heat and all other conditions are equal, the object with the larger heat capacity will have the

• A. Highest final temperature
• B. Undefined final temperature
• C. Same final temperature
• D. Lowest final temperature

Answer: (D)

When the same amount of heat is added to two objects, the change in temperature depends on the heat capacity. The relation is q = C ΔT, so ΔT = q / C. With equal q, the object that has a larger heat capacity experiences a smaller temperature rise. Since they start at the same initial temperature, the one with larger C ends up with a lower final temperature. In other words, higher heat capacity means the object heats up less for the same amount of heat, so its final temperature is the lowest.
