urgent:investigating concentration of acid

[helloying]

how do i differerniate a weak acid and a strong acid by reacting it with a alkalis and measuring the temperature? Which one will give me a higher temperature change? or will they both be the same?

A more concentrated (stronger) acid will give the higher temperature change if reacted with an alkali. However, the concentration of the alkali used for reaction must remain constant.
