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)`

Text Solution

Verified by Experts

The correct Answer is:
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`
