We add the same amount of heat to ten grams of each of the following substance at `20^(@)C`. Which of the samples show the lowest temperature change?A. `Al (s)`B. `C_(6) H_(6) (l)`C. `Hg(l)`D. `H_(2) O (l)`

Answer» Correct Answer - D
The higher the specific heat for a substance, the more heat is required to raise a given mass of sample by a given temperature change, so the less its temperature changes by a given amount of heat. Water with the highest specific heat undergoes the smallest temperature change. The ranking from lowest to highest final temperature is
`H_(2) O lt C_(6) H_(6) lt Al M lt Hg`
