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

Answer»

`5^(@)C`
`10^(@)C`
`25^(@)C`
`20^(@)C`

Solution :No DOUBT heat evolved during neutralisation of `250cm^(3)` of eacch 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 sam temperature rise is noticed.
