Question

And assume that the specific heat of solution is the same as water 4.134 J/(g C). Students used two thermometers in Thermo lab If both thermometers consistently read temperature exact!/1 0 degree higher than the actual temporal how does this affect the experimental molar heat of neutralization? Since the temperature differences ate used in all calculations this should not affect the molar heat of neutralization It has an unknown impact on the molar heat of neutralization. This will make the molar hoat of neutraBzalion higher This will make the molar heat ol neutralization lower

Explanation / Answer

There are two cases:

let T1 = termomether 1

and T2 = termometer 2

and

Ta = initial T

and Tb = final T

CASE 1:

we use T1 to measure Ta and Tb; then the difference will cancel the +1 unit; no effect in calculation of neutralization enthalpy

CASE 2:

we use T1 to measure either Ta or Tb; and T2 to measure Tb or Ta respectively;

the effect will have differnce of 1 C

most likely case is CASE 1

so choose A
