250 mLof 0.1 M HCL and 250 mL of 0.1 M KOH, both being at the same temperature, are mixed throughtly and the temperature rise is found to be DeltaT_(1). If the experiment is repeated using 500 mL each of the two solutions and DeltaT_(2) is the temperature rise, then which is true?

Answer»

`DeltaT_(2)gt2DeltaT_(1)`
`DeltaT_(1)=2DeltaT_(2)`
`DeltaT_(1)=DeltaT_(2)`
None of these

Solution :In the second EXPERIEMENT, the heat produced is twice that in first case but at the same TIME thermal capacity of the resulting solution (twice as that in first case) is doubled. Hence, temperature rise will be the same.
