A solution is 500 ml of 2 M KOH is added to 500 ml of 2 M HCl and the mixture is well shaken. The rise in temperature T1 is noted. The experiment is then repeated using 250 ml of each solution and rise in temperature T2 is again noted. Assume all heat is taken by the solution
A
T1 = T2
B
T1 is 2 times as large as T2
C
T2 is twice of T1
D
T1 is 4 times as large as T2
Answer
T1 = T2
Explanation
Solution
Q = m S ΔT1̃2QR=2mS DT1
̃ So, ΔT1 = ΔT2
