When `50 cm^(3)` of a strong acid is added to of an alkali, the temperature rises by `5^(@)C`. If `250 cm^(3)` of each liquid are mixed, the temperature rise would be

A

`5^(@)C`

B

`10^(@)C`

C

`25^(@)C`

D

`20^(@)C`

Text Solution

Verified by Experts

The correct Answer is:
A
No doubt heat evolved during neutralisation of `250cm^(3)` of each acid and base is five time the heat evolved during neutralisation of `50cm^(3)` of each acid and base but the quantity if solution taking heat is also five time and thus same temperature rise is noticed.
