Question

A solution of $500$ ml of $0.2$M $KOH$ is mixed with $500$ ml of $0.2$M $HCl$. It is stirred and the rise in temperature $T_1$ is recorded. The experiment is repeated using $250$ ml of each solution and the rise in temperature $T_2$ is recorded. Now, choose the correct relation between $T_1$ and $T_2$.

• A. $T_1=T_2$
• B. $T_1=2T_2$
• C. $2T_1=3T_2$
• D. $T_2=2T_1$

Answer 1

The correct option is A $T_1=T_2$

Temperature is an intensive property. So, it does not depend upon the number of moles or amount taken. Therefore, rise in temperature $T_1$ will be equal to rise in temperature $T_2$.
