Question

A careless scientist is about to measure the heat capacity of a calorimeter using the procedure described in this experiment. The scientist misreads the burette and dispenses 95.00 mL of water rather than the required 75.00 mL into his calorimeter. If the scientist presumes that the volume was 75 mL, what effect will this error have on the determination of the heat capacity (Cp)of the calorimeter?

a) The calculated Cp will be too low.

b) (T2 - T1) will be different but Cp will be the same.

The increased mass of water will prevent any difference.

The calculated Cp will be too high.

a) The calculated Cp will be too low.

b) (T2 - T1) will be different but Cp will be the same.

The increased mass of water will prevent any difference.

The calculated Cp will be too high.
