A 1.0g sample of substance A at 100^(@)...

A `1.0g ` sample of substance `A` at `100^(@)C` is added to `100 mL` of `H_(2)O` at `25^(@)C`. Using separate `100 mL` portions of `H_(2)O`, the procedure is repeated with substance `B` and then with substance `C`. How will the final temperatures of the water compare ?
`{:("Substance","Specific heat"),(A,0.60 J g^(-1) "^(@)C^(-1)),(B,0.40 J g^(-1) "^(@)C^(-1)),(C,0.20 J g^(-1) "^(@)C^(-1)):}`

A

`T_(C) gt T_(B) gt T_(A)`

B

`T_(B) gt T_(A) gt T_(C)`

C

`T_(A) gt T_(B) gt T_(C)`

D

`T_(A) = T_(B) = T_(C)`

Text Solution

Verified by Experts

The correct Answer is:
C
Substance A has more value of specific heat than B and C so it will raise the temperature of water more than B and C.
